This is a rare TV torn down for your viewing pleasure. Worlds smallest full color CRT TV. This one was offered to me, and it is now in my collection of small TVs.
this was one of my natural passions. i took apart a vcr wen i was 11 or so. i didnt know what i was doing & couldnt get it back together. then at 21 in my studio apartment. worked on my electronics & motherboards, bought my first sayderning iron, & was always frustrated by my lack of supplies and resorces to get them. i was driven though & extreamly focused, this was one thing that kept me alive. i would get so involved id forget about food and not feel my apitite all day.
I took electronics in high school back in the late 70's. Analog radio and TV mostly. The instructor told us that battery powered TV was impossible due to the high voltages needed to run the CRT. It amazes me how far we have come.
They had battery operated TVs back in the 1970s, and I've seen a prototype for a battery operated pocket TV with a B&W CRT screen that dated from the 1960s. Your teacher was wrong even then.
I'm quite fond of "MatsuNatPanaTechnics" kit myself, the quality and design always seems top notch & like they didn't just build them for a purpose but with genuine passion too.
So cool to see such a rare amall vintage TV from Panasonic. Thank you for sharing this video with us, love the channel, can't wait to see the next video
I have the black & white UK version of this Panasonic, I am amazed to see a colour version was also made. Mine uses conventional batteries and still works perfectly!
I had a Casio in the 90s and I figured out how to attach the output on my VCR to the antenna to watch videos. It was just for fun since the screen was way too small for that sort of thing. You'd think pocket size TVs would be extinct now in the smartphone age but they're still around
Many years ago, back in the mid 70's, no, wait, early 70's a buddy of mine at Fort Bliss had a little TV sort of like that, but it had AM/FM on it as well. I don't recall the brand name, but the TV Screen was about the same size, it would pop up when you hit the right button. The neat thing was that it looked every bit the radio, so when we pulled Arms Room Guard duty, the Sergeant of the Guard would allow us to take it with us to our guard post, which, because of some recent break-ins at the Fort had us behind locked doors, they gave us a .45 with three rounds of ammo to defend the Arms Room. So we would take the 'radio' with us and when the doors were locked behind us, we could pop up that screen and watch TV to kill the 3 hour shift, then when it was the next guy's turn, if he were in on the deal, you could leave it for his use. We never did get caught, but after I was promoted to Sergeant, and pulled Sergeant of the Guard, I was on to the con and refused to allow the TV down in the chamber. Funny how that little stripe can change a nice guy to an asshole! Well I looked at it as obeying the regulations.
That's one nice unit, very clever designers :-D i can't imagine how they made the phospher mask, crt's are a work of art. You are dam right on the capacitors, it would have been dead years ago on smd types. 10 to 11kv!!! that's enough to run a 12 inch black and white, no touching that anode cap :-D. I made a t.v from a black&white tube+pcb from a dead video camera, finding a tuner module small enough was a pain, then creating 32v for the tuning was the next problem. i used a tda200X for the audio. An old c.b radio case to mount it in was ideal, all metal :-)
By comparison a B/W tube of that size about 3kv. A 9" security monitor runs about 10kv. I used to have a small 5" color set, a citizen, and I do currently have a few small B/W sets with 4" tubes kicking around. The smallest color CRT I have in my little 8" trinitron. They made a smaller one, 3.7" and of course the much more rare indextron tube.
Yup... the phospers and also that little square sheet of metal with all those tiny holes through it behind the phosphers... definitely intriguing, zx8401ztx... they must have had very precision micro-lasers to punch that shadow-mask out
Im not sure how they did it, and i don't know if they had a laser that good all those years back. I still think the c.r.t was a clever way to display pictures, it had a life time that was longer than modern tv's. Modern stuff seems to change every few years to the next wizz bang pocket empty-ing idea, it stays unreliable though, funny that lol.
I get so nostalgic watching old small portable tvs like this. My grandmother had one that she used camping and I wanted it so bad. I catch myself thinking that it would be cool to have one. Then I remember I hold in my hands a device that can do this and more, with a better and bigger screen. It's still so cool to look back at old technology like this.
That's just it. Now with a cell phone you can watch pretty much anything you want. You have basically a studio in your hand. We take this for granted today, but it wasn't that long ago that we were still using vacuum tubes to generate s picture. You have to give them credit for doing what they did back then and the thing with these old devices is, looked after they will probably still function in another 30 years even though by then we will have nothing to produce a signal on them. I have a set of display cases that my wife's grandfather made that are an ugly color. This fall I will repaint them and then my old tech collectables will be put on display. My old cameras, and various small TVs as I have a few. In addition to this I have a 2" Sony watchman, 4" watch cam monitor, and some old camera. Have all the old video formats. Beta. VHS, VHSc, 8mm. 2 piece portable units. This little color tube though has to be one of the rarer pieces I own. Even though in this video I was intending to ship it back, the owner of it decided to sell it so I ended up with it.
Back in the 80's I bought one from a company called "Sharper Image", I traded it for a UNISONIC XL990 which has a 2" screen, AM/FM radio and takes 6 AA battery's. I still have it like new in mint condition, it also has a slide on magnifier and a leather case.
I envy you this device. )) It is interesting, or rather we forgot that the image on any small CRT screen could be comfortably watched - good black color and its distance from grayscale, contrast, sharpness in any format, low response ("pixel" immediately goes out , if not restored), natural blur in motion (visible on fast-scrolling text or sports broadcasts, which is good for the eyes, unlike some LCDs), ... The quality of the then CRT screens is reflected in the fact that each point of the screen was its light source, as solved in OLED and QLED. I also once succumbed to the "mainstream" and destroyed all the CRT screens in the house. Then I had to get them back for special purposes ...))
@@skeetrix5577 don't be pedantic , colour is the proper way to spell it ..the us had to cut letter's out of proper English because of a lack of ink during a war, so they started to shorten their word's and then they just couldn't be assed correcting it .... ever since.
Wow that HT voltage is plenty high enough for such a tiny CRT! This is so cool, would love to find one of these just for the same reasons as you, the tiny "proper" shadowmask CRT is such a cool thing even if not the most practical. I'd certainly at least watch a couple of films on it just for the novelty. Speaking of which, more John Wayne on the Bush mini b/w CRT shortly i think! If i ever happen to chance across one of these (even more unlikely in PAL-land) I'll be sure to let you know Dave.
I have a Sony black n white TV.but I have a little transmitter to hook up to a vcr one time,but still do ant a little fat screen TV that does analogue and digital to.i have not worked on this one yet but will.ramsey had TV transmitter kit so you can use it on old TVs.thanks.
In case you were wondering (You probably weren't) you CAN in fact play light gun games like Duck Hunt on this TV. The experience is surprisingly accurate actually...I mean it's hard to see at any sporting distance, but it functions very accurately.
Awesome video. I think Panasonic intended this to be a halo product for them to show the companies technical abilities. Maybe someone can chime in but I also thought they made a color viewfinder in one of their video cameras around this time as well. Not sure if it was a CRT or just an optical system.
There were a number of small CRT's in use in camcorders though I'm sure very few were color. I suspect the tube in this unit was common to those as well. Nobody has discovered yet that these CRT's can be had from thrift shops for a pittance, but a cool source of parts and ready to accept NTSC signals and battery power.
I fellow I knew once had a higher quality camcorder from late 70s with a color monitor. Only one I remember seeing. I once checked out color CRT TV with about 2" screen in a store. It was set up like a watchman. The pixel dots made it hard to see the picture without backing up, then it was too small to see far away.
Were you able to get the debris from behind the plastic cover over the CRT? I have the CT-3311 and I am wanting to get behind the plastic to clean it out
Thanks for sharing... that's definitely one of the historic pieces.... imagine one of those Panasonic CT-101's sitting on top of an RCA CTC-100 :-) ... that would be a trip!..lol :-D
Right on... yep... that one's definitely a 'holy-grail' set...the RCA CTC-100 :-) ... not too many videos about them on YT, relatively... shango066 did one several years ago: ua-cam.com/video/ot79p-37A6Q/v-deo.html.... another guy has one now and is currently restoring it.... the 15GP22 tube in it is reading strong on the CRT tester, and all the electrolytic caps have been changed, so far.... that series starts here: ua-cam.com/video/NAOdBcN31mg/v-deo.html That's all I found so far...
Cool... I just found this one... beautiful view of that awesome perfect combination of the right phosphor mixes and technology to bring out the capabilities of those phosphors: ua-cam.com/video/2USjriAK80E/v-deo.html
When I think about all those era tv's I threw away over the years when I was in the servicing business, I kick myself for not having the foresight to hang on to a couple dozen of them, they are history and valuable.... Not to mention all the tubes and components from the 60s and 70's that would be preserving history of electronics. Nowadays,we simply throw everything away with no conscience of historical value.!! I miss those early days of TV service . Best wishes my friend.!
YesI have hung onto a few. I unfortunately tossed my old 34" CRT HD set as it was too heavy to move. I do have a few CRT sets that I am keeping as collector items. This 1.5 is going in my collection. I have a few small B/W sets, and an 8" sony trinitron. I have a KV1365 and 1965 sony. These were non-remote sets with video input using optical chassis isolation. I have a mitsubishi 26" as well, and the very last Sony 21" Wega perfectly flat trinitron model that they made. This was the last of the analog only sets. I have a JVC multi system set as well and a few industrial monitors. Just hung onto them for the memories of the past when I was servicing. The modern LCD sets I don't have much interest in. I do like Plasma. I just thing the way they work is cool compared to the boring LCD. I like restoring old tube gear.
12voltvids ...... I think we've all had many of those brands that I couldn't give away just a few years ago, as I said I wish I hung onto a lot of that material and tv's that were lying around and seemed to be outdated only to now realize they are valuable, my 35 inch Mitsubishi with the wood cabinet and worked PERFECTLY , was unfortunately thrown away when I moved because it was to heavy to take with me...that was a sin.!! Anyway, best wishes and keep plugging away.
What is funny is last spring during free junk day I picked up 4 small 14" and 10" CRT TVs that people put at the curb. I hung onto the 21" sony because it was in pristine condition, and has a perfect picture. The other 3 sets I threw up on craigslist, and sold them all within 2 days to 8bit game console collectors. The new flat screen TVs are impossible to play old games on due to the delay between the video signal received and display on the panel. CRT sets have no such delay. This 4 - 5 frame delay makes it impossible to shoot at something moving on the screen as by the time you see it, the shot window is closed. So game console collectors want CRT sets. Never though I would see hat happen.
I wish someone would manufacture small CRT’s for mini arcades. LCD/TFT/LED displays work, but they have an unofficial cheap feel and look to them. We need some modern color tubes!!!
Nothing like playing arcade games on a real CRT. Especially if it is a heavy used tube with lots of image burn just like the real arcade games left running 24/7
Awesome little TV! I've only seen the B&W version. I remember some Sanyo TV's used similar ceramic type stand up modules. They we're in the vertical section.
You know, this reminds me a lot of the monitor system that Caroll Spinney wore during his forty five years of performing Big Bird from Sesame Street. If anything, this probably isn’t that far away from that.
Does anyone know if the black and white version of this TV magnifier will fit the color version in this video? I just got hold of a CT101 in excellent condition and working great even with rebuilt rechargeable battery but it has no magnifier. thanks
I knew from the start that it was not indexed based, only sony did, it’s weird to see such giant device with such small screen but that was the 80’s, nowadays, handhelds such as the smartphone are way smaller but do have bigger screens on it.
a while ago, i joined the CT-101 club. Even have the box. can provide a pic if requested. Mine needed some power supply work as the original SMPS supply was on its way out and interfered with the screen, creating scrolling lines. i replaced all that with a couple of LM317 regulators and pots to adjust to the correct voltages.
Ct101 is a cool little tv. Going to rebuild the battery pack on mine one of these days. I don't actually watch it, just show it off from time to time like my old cameras.
I love how much of an engineering marvel CRTs are, it's a shame no one makes them anymore as they still have advantages over LCDs as well as their disadvantages, imagine with modern electronics how much more the electronics could be shrunk down to save space.
These were indeed cool devices. Had a buddy when I was in the Army that had one of those, he used to lend it to us when we had arms room guard, they would lock us up down in a small outer office between the outdoors and the Arms room vault where all the M-16's and such were stored. We had a Model 1911A1 .45 ACP Pistol and were allowed to bring a radio to keep us awake for our 2 hour shift, his TV looked enough like a radio that it passed inspection before we took our post. This way we could watch TV and stay awake instead of reading and listening to the radio, which had a tendency to put me to sleep back then. They were good for that. I had a small Crown brand of black and white TV with AM/FM radio built in that I picked up in Tokyo on my way home from Vietnam, it worked good took a large adapter with 9 D cells, or could plug into a car with a 12 volt plug. I ended up selling that to a fellow who worked as a night watchman, he mounted it in his car that he used to patrol the areas of his charge. Said the TV worked great for that. It had a resistor burn up in it when I had it, I took it to a TV repair shop and they said they couldn't get a schematic for it since it was never sold in the USA, so I just took a bit of wire and wrapped it around the two legs of the burned out resistor and it came back to life. I have no idea how long it lasted working like that since I was transfered from Texas to the DC area, and never saw the fellow again.
@@12voltvids $85 plus shipping. They don't pop up on ebay too often at all.. there was one on an auction up before I snatched this one, went for like $170. Caught me off guard, way past my $100 max bid, lol
@@speedyink That's pretty good. I think that is about what I paid. I got this one from a viewer that offered me the tektronix scope I use now as a donation, and offered me his 101 for I think it was 80 bucks.

@@12voltvids Stupid question if I may, but it would be nice to get a second opinion. I don't know if you got the rechargeable battery pack at all with yours, but it basically looks like just 4 Ni-Cad AA's in a plastic holder. I'm thinking of just buying some new Ni-Cad batteries and in theory, good as new, right? I mean, I don't see anything that could go wrong, but I'd would be so sad if something went wrong when i tried to charge, you know?
B/W were quite common compared to the color version. Sony had several watchman models that had a flat b/w tube ranging from 2 - 4". They were working on a flat color tube too but LCD came out a year or so later and tiny CRT development ended. These little tubes were initially developed for the camcorder market. Hitachi (RCA) used a beam index tube on their viewfinder.
Those analog channels are available in my house and only my house. I have a stack of professional CATV modulators that allow me to send video signals around the house. I currently have 2 MTS stereo modulators and 5 mono moduators.The 2 MTS are used to send programming in stereo sound, mainly music oriented programs. One just plays youtube concerts that have been saved before they were taken down. One sends my security cameras throughout the house and the others an analog feed from a couple of cable boxes. One for example stays on a news channel so I can watch it on any TV. I still have a few old TVs that only have analog tuners. This allows me to use these sets and also provides me with test signals when working on old AV gear. One channel, has just video footage I shot. That way I don't get hit with copyright if I show it on YT. I did a video showing the rats nest in my communications closet several years ago. Lots of coax and splitters to combine the signals. On top of that, off air digital signals are also in the MUX, so on a digital capable TV, I see both the analog and off air digital signals.
probably the neck of the crt is too thin to accomodate in-line, and delta arrangement is more space efficient for three guns in a round neck. The phosfor and shadow mask follow that gun arrangement. The relative long neck compared to the screen diameter make up for the convergence issues associated with delta.
No. Single gin color CRT, have no registration or purity error. A single gun color CRT is known as a beam index tube. Sony calls theirs the 'indextron" tube. How it works is there is a 4th stripe added to the back side of the tube added to the red stripe. This 4th color stripe emits UV light which is picked up by detectors mounted on the bell of the tube that look inside to the back of the tube. Flashes of UV light synchronize the color multiplex circuit that switches between the R G and B video signals to drive the single beam as it sweeps across the screen. Conventional 3 gun tubes use a shadow mask, or aperture grill to align the electron beams from each gun to their specific color dot. Because the shadow mask is metal, it can pick up a magnetic charge and this will repel the electrons as they pass through and cause purity errors. So this mask is demagnatized at every turn on by the degauss circuits. Also as the beam travels across the screen the distance changes slightly between the 3 guns, and this is controlled by the convergence coils, and fixed magnets. The coils provide a dynamic signal that changes with the sweep position to keep the 3 beams aligned with the correct holes in the shadow mask as the beam scans it.
plug in a composite source into an rf modulator (maybe a vcr), take the coax cable and strip it, attach the two inner wires to the two clamps of one side of the alligator clip
Are you sure the gun is inline, it would not work correctly with a delta shadowmask. Plus the neck is so thin a delta gun assembly is the most space efficient.
It's a commercial head end modulator with +60dB output. Hook an antenna to it, and it will broadcast a few hundred feet. I have 4 of them. Set to channel 5, 7, 9, 12. The channel 12 is in MTS Stereo sound, and I use it to play canned concerts I have ripped from youtube, and send them throughout the house. Commercial modulators were designed to be fed into signal mixers to combine all the signals the cable company was going to send into the cable. Once all the signals are mixed (and levels balanced) they were fed to the amplifiers that sed the signals out to the community.
Easy, just chain an HDMI to component converter with a component to RF converter and connect to an amplified antenna (with the amplifier connected backwards). You can get all three parts for around $60 on Amazon.
12VOLTSVIDS, What is the differences between a sync signal compared to a deflection signal? There is H&V sync signals and H&V deflection signals i don't know what are the differences between them
The sync signals are just pulses that control the deflection signals, which through capacitors and coils form the sawtooth sweep signals that drive the deflection yoke coils.
@@12voltvids thanks, but what are deflection signals, are they pulses or what do deflection do to the CRT circuit? What I mean is that H&V sync signals are the position coordinates for the CRT display but also the H&V Deflection signals are also the position coordinates for the CRT display image so I'm confused on the differences between sync signals and deflection signals i don't understand the differences or what the do. Can you explain more in detail what deflection signals are doing because there is vertical deflection signals and horizontial deflection signals
@@billwilliams6338 The sync pulses are just that. Pulses that trigger the deflection circuit to synchronize the sweep circuits. In the case of the horizontal circuit they start the beginning of horizontal sweep for each line at a frequency of 15.975khz this triggers the horizontal output transistor or tube which creates a pulse in the primary of the flyback and the horizontal yoke winding. Along with the linearity coil and capacitors this pulse is turned into a sawtooth waveform. The vertical sync pulse is at 60 Hz (ntsc countries), which is used as a reference for an oscillator in a sawtooth generator circuit that generates the vertical sweep or deflection signal. This is done with active and passive components in the vertical circuit. Namely capacitors of various values. This signal is applied to the vertical yoke coil. These are some of the more complex circuits in a crt display and trying to explain it in a short message won't do any of us any good. There are books on television that explain the theory of how it's done. The important thing to remember is the sync signals syncronise the sweep curcuits. The sweep circuits will operate in free run without them such as when no signal but the sync pulses must be there to lock the picture. If you remember what the analog scrambled cable tv channels looked like. Well that is what happens to video with no sync. The picture flops and rolls. No deflection well you get a horizontal line for loss of vertical and a vertical line for loss of horizontal. Perhaps a video demonstrating this would help.
@@12voltvids thanks for the help. Just to make is clear you get H&V deflection signals from the sweep circuit? Like you said the sync signals keep the sweep circuit in sync but the sweep circuit will output H&V deflection signals to the H&V yokes? The Horizontal Deflection outputs a PULSE signal to the Horizontal Yoke and Flyback. The Vertical Deflection outputs a PULSE signal to the Vertical Yoke. Any reasons why they are using a YOKE for both the H&V . A Yoke is just a coil of wire wrapped around like a inductor I'm not sure why they are using YOKES to do the H&V deflections on the CRT. The H&V Deflections are outputting signals to the H&V yokes to tell the CRT display what positions coordinates to be BEAM positioned at on the CRT screen? The Flyback is the CRT anodes High voltage which is measured 19Kv to 26Kv but I don't know what the Flyback is doing to the H&V deflection or is the Flyback job only to just give High Voltage to the CRT tube thats its only purpose of the flyback? The B+ voltage have a trim pot if the B+ trim pot is not set correctly it will display a scrambled image just like having a Sync problem. So I'm confused about what the B+ voltage is ment for. This is a young techs trap because you will think you have a sync circuit issue when its theh B+ trim pot set to the wrong voltage which is display a scramble image.
@@billwilliams6338 There are 2 yoke windings. One moves the beam side to side (horizontal ) and the other up and down. (vertical). These go to the specific output circuits. The flyback generates the HV for the second anode, focus and usually the screen. On some hot chassis sets the horizontal output drives the flyback which doubles as the main. Transformer so all the lower voltages are also derived from the flyback. The reason is for voltage control. Only need to regulate the raw b+ which is 130 on most sets. Regulate that and all the others will be correct. On newer sets they used a seperate smps for the lower voltages but the HT, focus and screen b+ which was around 200v always comes from the flyback.
B/w CRT down to .5" were made for eyepiece. There was a 1.25" beam index color made that used external sensors to syncronize the color circuits. This one is the smallest 3 gun conventional color tube and even though it may have been the pro camera division that designed it camera operators didn't want this because it wasn't sharp enough for critical focusing.
good one. But the best one is one model that makes COLOR TV with a BLACK/WHITE only CRT, because the fidelity is too superior, no grid, continous phosphor screen, just a normal B/N CRT and does color.
Not a normal be crt, beam index still has phosphor stripes. That hybrid that JVC had out used a bw crt but had LCD shutter and color filters to make the color.
Right on... some years ago I had a little Casio LCD color set ... I remember it only had up/down buttons for tuning and one had to wait for the thing to move along the screen until it locked-on to the next channel ... sure was neat stuff back then :-)
Yes just like my Panasonic LCD. The difference between the casio LCD and Panasonic LCD was casio used a super twist LCD and Panasonic used a TFT LCD which is the same as most TVs use today. Newer high contrast models use IPS screens.
I have the same set and did a repair video on my channel. They make better pictures than what you can show on you tube. The picture just doesn't translate. The cabinets for these sets were horsedung. Most of them are real brittle now, as was mine. Looks like that example was in really good shape. A real cool set for collectors of the micro's and nostalgia. But not something you want to watch for 2 hours, at least I don't being over 50 years of age! LOL!
This one is in my collection now as I had an offer to buy it, and it is in pretty good shape. Yes panasonic plastic was dogshit. Terrible stuff. I remember pulling the back off a 32" TV to service it and it shattered into pieces in my hands. Recycled styrofoam is the joke we used to make about their cabinets. No, this is not something to be watched, but just for the cool factor to rurn it on once in awhile and admire the technology that went into making a shadow mask tube of that size. Beam index was the norm for small tubes, but this one is the real deal. A shot from it has made it into my updated opening logo.
I miss the dynamic convergence circuits. This one is probably a delta shadow-mask tube with an in-line gun. Like almost all color computer monitors from the early '80s through the mid '00s except Trinitron and its knock-offs (Mitsubishi Diamondtron and LG Flatron). Ha! Scott has the service manual. Pause at the specs. The service manual states that it's a 30° deflection angle *in-line* tube! ua-cam.com/video/OoJNqLpPpcc/v-deo.html
I have one of those too but the color filters for the beam detector is missing so it only shows b/w. Beam index is a monochrome tube. 1.25" is big for that. I have a .5 monochrome. This is the smallest color tube, with 3 guns and a shadow mask. Beam index has 1 and no shadow mask so that doesnt count.
@@12voltvids I know it doesn't count lol. I have one of those itty bitty Video8 cameras with a CRT viewfinder, smallest CRT I know of. I am still blown away by the resolution of that thing! I am trying to find a working beam index tube, I want to make a little color travel television!
@@mandarin1257 They are color only in the respect that they display a color image you could get the same effect if you attached a color stripe filter t ok a black and white screen. Indextron is a type of beam index tube. They are both a single gun tube but work in totally different ways. In both however it is about timing the beam so that if you want if you want red, the beam is only switched on during the time the beam is passing over the area where the red phosphors or red filter is. In a conventional beam index tube a yellow and blue detector points at the screen (in the viewfinder shell of the camera) so the color sync circuit knows where the beam is. On the Sony indextron version an extra uv stripe is added between the red and green stripes that flashes uv light every time the beam hits it. This strobing uv light it detected by detectors attached to the cell of the crt looking at the back of the screen. This little tv uses a conventional color crt, which had 3 guns, 3 lenses, and a shadow mask. Beam index has none, which means they can be much smaller because there is nothing more in them than a monochrome tube.
Make circuit of oscilloscope that run on video input composite of TV with out open any tv or any other device. it make on working tv or video input based devices or monitor but not used A2D based circuit like Arduino or other digital circuit Useing analoge circuit this is awesome new idea to make every video based devices into oscilloscope. Can make tow different frequencies horizontal and vertical,and then distrube by injecting measuring signal work oscilloscope.

I don't recall the brand name, but the TV Screen was about the same size, it would pop up when you hit the right button. The neat thing was that it looked every bit the radio, so when we pulled Arms Room Guard duty, the Sergeant of the Guard would allow us to take it with us to our guard post, which, because of some recent break-ins at the Fort had us behind locked doors, they gave us a .45 with three rounds of ammo to defend the Arms Room. So we would take the 'radio' with us and when the doors were locked behind us, we could pop up that screen and watch TV to kill the 3 hour shift, then when it was the next guy's turn, if he were in on the deal, you could leave it for his use. We never did get caught, but after I was promoted to Sergeant, and pulled Sergeant of the Guard, I was on to the con and refused to allow the TV down in the chamber. Funny how that little stripe can change a nice guy to an asshole! Well I looked at it as obeying the regulations.
That's one nice unit, very clever designers :-D
i can't imagine how they made the phospher mask, crt's are a work of art.
You are dam right on the capacitors, it would have been dead years ago on smd types.
10 to 11kv!!! that's enough to run a 12 inch black and white, no touching that anode cap :-D.
I made a t.v from a black&white tube+pcb from a dead video camera, finding a tuner module small enough was a pain, then creating 32v for the tuning was the next problem.
i used a tda200X for the audio.
An old c.b radio case to mount it in was ideal, all metal :-)
By comparison a B/W tube of that size about 3kv. A 9" security monitor runs about 10kv. I used to have a small 5" color set, a citizen, and I do currently have a few small B/W sets with 4" tubes kicking around. The smallest color CRT I have in my little 8" trinitron. They made a smaller one, 3.7" and of course the much more rare indextron tube.
Now I'm wondering what my Binoc TV's 2nd anode voltage is.... it's screen is just a tiny bit bigger than the CT-101's screen, and is B/W.
Yup... the phospers and also that little square sheet of metal with all those tiny holes through it behind the phosphers... definitely intriguing, zx8401ztx... they must have had very precision micro-lasers to punch that shadow-mask out
Im not sure how they did it, and i don't know if they had a laser that good all those years back.
I still think the c.r.t was a clever way to display pictures, it had a life time that was longer than modern tv's.
Modern stuff seems to change every few years to the next wizz bang pocket empty-ing idea, it stays unreliable though, funny that lol.
Right on
I get so nostalgic watching old small portable tvs like this. My grandmother had one that she used camping and I wanted it so bad. I catch myself thinking that it would be cool to have one. Then I remember I hold in my hands a device that can do this and more, with a better and bigger screen. It's still so cool to look back at old technology like this.
That's just it. Now with a cell phone you can watch pretty much anything you want. You have basically a studio in your hand. We take this for granted today, but it wasn't that long ago that we were still using vacuum tubes to generate s picture. You have to give them credit for doing what they did back then and the thing with these old devices is, looked after they will probably still function in another 30 years even though by then we will have nothing to produce a signal on them. I have a set of display cases that my wife's grandfather made that are an ugly color. This fall I will repaint them and then my old tech collectables will be put on display. My old cameras, and various small TVs as I have a few. In addition to this I have a 2" Sony watchman, 4" watch cam monitor, and some old camera. Have all the old video formats. Beta. VHS, VHSc, 8mm. 2 piece portable units. This little color tube though has to be one of the rarer pieces I own. Even though in this video I was intending to ship it back, the owner of it decided to sell it so I ended up with it.

Not wireless. Hardwired.
I envy you this device. )) It is interesting, or rather we forgot that the image on any small CRT screen could be comfortably watched - good black color and its distance from grayscale, contrast, sharpness in any format, low response ("pixel" immediately goes out , if not restored), natural blur in motion (visible on fast-scrolling text or sports broadcasts, which is good for the eyes, unlike some LCDs), ... The quality of the then CRT screens is reflected in the fact that each point of the screen was its light source, as solved in OLED and QLED. I also once succumbed to the "mainstream" and destroyed all the CRT screens in the house. Then I had to get them back for special purposes ...))

Sweet Little TV...
Awesome video. I think Panasonic intended this to be a halo product for them to show the companies technical abilities. Maybe someone can chime in but I also thought they made a color viewfinder in one of their video cameras around this time as well. Not sure if it was a CRT or just an optical system.
absolutely amazing!
There were a number of small CRT's in use in camcorders though I'm sure very few were color. I suspect the tube in this unit was common to those as well. Nobody has discovered yet that these CRT's can be had from thrift shops for a pittance, but a cool source of parts and ready to accept NTSC signals and battery power.
Most of the color crt CAMERA VIEWFINDERS WERE BEAM INDEX TYPES.
I fellow I knew once had a higher quality camcorder from late 70s with a color monitor. Only one I remember seeing.
I once checked out color CRT TV with about 2" screen in a store. It was set up like a watchman. The pixel dots made it hard to see the picture without backing up, then it was too small to see far away.
Were you able to get the debris from behind the plastic cover over the CRT? I have the CT-3311 and I am wanting to get behind the plastic to clean it out

When I think about all those era tv's I threw away over the years when I was in the servicing business, I kick myself for not having the foresight to hang on to a couple dozen of them, they are history and valuable....
Not to mention all the tubes and components from the 60s and 70's that would be preserving history of electronics.
Nowadays,we simply throw everything away with no conscience of historical value.!!
I miss those early days of TV service .
Best wishes my friend.!
YesI have hung onto a few. I unfortunately tossed my old 34" CRT HD set as it was too heavy to move. I do have a few CRT sets that I am keeping as collector items. This 1.5 is going in my collection. I have a few small B/W sets, and an 8" sony trinitron. I have a KV1365 and 1965 sony. These were non-remote sets with video input using optical chassis isolation.
I have a mitsubishi 26" as well, and the very last Sony 21" Wega perfectly flat trinitron model that they made. This was the last of the analog only sets. I have a JVC multi system set as well and a few industrial monitors. Just hung onto them for the memories of the past when I was servicing. The modern LCD sets I don't have much interest in. I do like Plasma. I just thing the way they work is cool compared to the boring LCD. I like restoring old tube gear.
12voltvids ...... I think we've all had many of those brands that I couldn't give away just a few years ago, as I said I wish I hung onto a lot of that material and tv's that were lying around and seemed to be outdated only to now realize they are valuable, my 35 inch Mitsubishi with the wood cabinet and worked PERFECTLY , was unfortunately thrown away when I moved because it was to heavy to take with me...that was a sin.!!
Anyway, best wishes and keep plugging away.
What is funny is last spring during free junk day I picked up 4 small 14" and 10" CRT TVs that people put at the curb. I hung onto the 21" sony because it was in pristine condition, and has a perfect picture.
The other 3 sets I threw up on craigslist, and sold them all within 2 days to 8bit game console collectors. The new flat screen TVs are impossible to play old games on due to the delay between the video signal received and display on the panel. CRT sets have no such delay. This 4 - 5 frame delay makes it impossible to shoot at something moving on the screen as by the time you see it, the shot window is closed. So game console collectors want CRT sets. Never though I would see hat happen.
Hi great video!! What RF modulator do you use? Keep up the great work very informative. 73's
I wish someone would manufacture small CRT’s for mini arcades. LCD/TFT/LED displays work, but they have an unofficial cheap feel and look to them. We need some modern color tubes!!!
Nothing like playing arcade games on a real CRT. Especially if it is a heavy used tube with lots of image burn just like the real arcade games left running 24/7

@@santoshmaharjanktm x-rays!
These were indeed cool devices. Had a buddy when I was in the Army that had one of those, he used to lend it to us when we had arms room guard, they would lock us up down in a small outer office between the outdoors and the Arms room vault where all the M-16's and such were stored. We had a Model 1911A1 .45 ACP Pistol and were allowed to bring a radio to keep us awake for our 2 hour shift, his TV looked enough like a radio that it passed inspection before we took our post. This way we could watch TV and stay awake instead of reading and listening to the radio, which had a tendency to put me to sleep back then. They were good for that. I had a small Crown brand of black and white TV with AM/FM radio built in that I picked up in Tokyo on my way home from Vietnam, it worked good took a large adapter with 9 D cells, or could plug into a car with a 12 volt plug. I ended up selling that to a fellow who worked as a night watchman, he mounted it in his car that he used to patrol the areas of his charge. Said the TV worked great for that. It had a resistor burn up in it when I had it, I took it to a TV repair shop and they said they couldn't get a schematic for it since it was never sold in the USA, so I just took a bit of wire and wrapped it around the two legs of the burned out resistor and it came back to life. I have no idea how long it lasted working like that since I was transfered from Texas to the DC area, and never saw the fellow again.

Wow my twin had one of those a 1986 BW version it looked just like that.
B/W were quite common compared to the color version. Sony had several watchman models that had a flat b/w tube ranging from 2 - 4". They were working on a flat color tube too but LCD came out a year or so later and tiny CRT development ended. These little tubes were initially developed for the camcorder market. Hitachi (RCA) used a beam index tube on their viewfinder.
Can see the convergence rings next to deflection yoke, which means it definitely is a conventional CRT. A beam index tube wouldn't require those.
In fact, it needs even more convergenge as this is a delta gun and not inline.
Where did you get that many analog channels?
Those analog channels are available in my house and only my house.
I have a stack of professional CATV modulators that allow me to send video signals around the house.
I currently have 2 MTS stereo modulators and 5 mono moduators.The 2 MTS are used to send programming in stereo sound, mainly music oriented programs. One just plays youtube concerts that have been saved before they were taken down. One sends my security cameras throughout the house and the others an analog feed from a couple of cable boxes. One for example stays on a news channel so I can watch it on any TV. I still have a few old TVs that only have analog tuners. This allows me to use these sets and also provides me with test signals when working on old AV gear. One channel, has just video footage I shot. That way I don't get hit with copyright if I show it on YT. I did a video showing the rats nest in my communications closet several years ago. Lots of coax and splitters to combine the signals. On top of that, off air digital signals are also in the MUX, so on a digital capable TV, I see both the analog and off air digital signals.
Wow that's so cool,
Now all I need is a potato chip bag

20:10 , why are the pixels in the PC CRT arrangement instead of the normal TV one?
probably the neck of the crt is too thin to accomodate in-line, and delta arrangement is more space efficient for three guns in a round neck. The phosfor and shadow mask follow that gun arrangement. The relative long neck compared to the screen diameter make up for the convergence issues associated with delta.
I want to buy this product please give me the buying details please
Do CRTs with one electron gun have convergence issues?
No. Single gin color CRT, have no registration or purity error.
A single gun color CRT is known as a beam index tube. Sony calls theirs the 'indextron" tube. How it works is there is a 4th stripe added to the back side of the tube added to the red stripe. This 4th color stripe emits UV light which is picked up by detectors mounted on the bell of the tube that look inside to the back of the tube. Flashes of UV light synchronize the color multiplex circuit that switches between the R G and B video signals to drive the single beam as it sweeps across the screen.
Conventional 3 gun tubes use a shadow mask, or aperture grill to align the electron beams from each gun to their specific color dot. Because the shadow mask is metal, it can pick up a magnetic charge and this will repel the electrons as they pass through and cause purity errors. So this mask is demagnatized at every turn on by the degauss circuits.
Also as the beam travels across the screen the distance changes slightly between the 3 guns, and this is controlled by the convergence coils, and fixed magnets. The coils provide a dynamic signal that changes with the sweep position to keep the 3 beams aligned with the correct holes in the shadow mask as the beam scans it.
How do you make/hook up the NTSC signal?
plug in a composite source into an rf modulator (maybe a vcr), take the coax cable and strip it, attach the two inner wires to the two clamps of one side of the alligator clip
Smallest in-line gun CRT. Interesting that they used a delta dot pattern.
Are you sure the gun is inline, it would not work correctly with a delta shadowmask. Plus the neck is so thin a delta gun assembly is the most space efficient.
I have a black and white like that. Not a Panasonic made in Japan sold under the Emerson name. It has the magnaifier also a AM/FM radio in it.
I didn't know these existed that small
They did, for a year or so. That's why they are so rare. They also cost as much as a console tv back in the day.
can be connected to a DVD player a playstation 4 and nintendo switch game console
I was thinking about that, and looking at the inputs it looks like you could wire it to a VGA cable and run a PC through the screen.
You can with some very simple modifications. Or an RF modulator.
Can you get shocked when you touch the internals or the crt tube?
Sure can. Plenty of places inside a CRT set with high voltage. After all it is a vacuum tube.
@@12voltvids even if it's battery powered?
Flyback transformer on this set steps the HV up to probably 10kv on that little tube and the focus grid is probably 1kv.

Awesome video instant subscribe!
Miss ya analog tv...... YES!
how did you set up your own tuneable tv station?
It's a commercial head end modulator with +60dB output. Hook an antenna to it, and it will broadcast a few hundred feet. I have 4 of them. Set to channel 5, 7, 9, 12. The channel 12 is in MTS Stereo sound, and I use it to play canned concerts I have ripped from youtube, and send them throughout the house.
Commercial modulators were designed to be fed into signal mixers to combine all the signals the cable company was going to send into the cable. Once all the signals are mixed (and levels balanced) they were fed to the amplifiers that sed the signals out to the community.
Easy, just chain an HDMI to component converter with a component to RF converter and connect to an amplified antenna (with the amplifier connected backwards). You can get all three parts for around $60 on Amazon.
In my opinion I think the most interesting part of the mini tv is the picture ray tube
Yes of course it is.

12VOLTSVIDS, What is the differences between a sync signal compared to a deflection signal? There is H&V sync signals and H&V deflection signals i don't know what are the differences between them
The sync signals are just pulses that control the deflection signals, which through capacitors and coils form the sawtooth sweep signals that drive the deflection yoke coils.
@@12voltvids thanks, but what are deflection signals, are they pulses or what do deflection do to the CRT circuit? What I mean is that H&V sync signals are the position coordinates for the CRT display but also the H&V Deflection signals are also the position coordinates for the CRT display image so I'm confused on the differences between sync signals and deflection signals i don't understand the differences or what the do. Can you explain more in detail what deflection signals are doing because there is vertical deflection signals and horizontial deflection signals
@@billwilliams6338
The sync pulses are just that. Pulses that trigger the deflection circuit to synchronize the sweep circuits. In the case of the horizontal circuit they start the beginning of horizontal sweep for each line at a frequency of 15.975khz this triggers the horizontal output transistor or tube which creates a pulse in the primary of the flyback and the horizontal yoke winding. Along with the linearity coil and capacitors this pulse is turned into a sawtooth waveform. The vertical sync pulse is at 60 Hz (ntsc countries), which is used as a reference for an oscillator in a sawtooth generator circuit that generates the vertical sweep or deflection signal. This is done with active and passive components in the vertical circuit. Namely capacitors of various values. This signal is applied to the vertical yoke coil. These are some of the more complex circuits in a crt display and trying to explain it in a short message won't do any of us any good. There are books on television that explain the theory of how it's done. The important thing to remember is the sync signals syncronise the sweep curcuits. The sweep circuits will operate in free run without them such as when no signal but the sync pulses must be there to lock the picture. If you remember what the analog scrambled cable tv channels looked like. Well that is what happens to video with no sync. The picture flops and rolls.
No deflection well you get a horizontal line for loss of vertical and a vertical line for loss of horizontal. Perhaps a video demonstrating this would help.
@@12voltvids thanks for the help. Just to make is clear you get H&V deflection signals from the sweep circuit? Like you said the sync signals keep the sweep circuit in sync but the sweep circuit will output H&V deflection signals to the H&V yokes? The Horizontal Deflection outputs a PULSE signal to the Horizontal Yoke and Flyback. The Vertical Deflection outputs a PULSE signal to the Vertical Yoke. Any reasons why they are using a YOKE for both the H&V . A Yoke is just a coil of wire wrapped around like a inductor I'm not sure why they are using YOKES to do the H&V deflections on the CRT. The H&V Deflections are outputting signals to the H&V yokes to tell the CRT display what positions coordinates to be BEAM positioned at on the CRT screen? The Flyback is the CRT anodes High voltage which is measured 19Kv to 26Kv but I don't know what the Flyback is doing to the H&V deflection or is the Flyback job only to just give High Voltage to the CRT tube thats its only purpose of the flyback? The B+ voltage have a trim pot if the B+ trim pot is not set correctly it will display a scrambled image just like having a Sync problem. So I'm confused about what the B+ voltage is ment for. This is a young techs trap because you will think you have a sync circuit issue when its theh B+ trim pot set to the wrong voltage which is display a scramble image.
@@billwilliams6338
There are 2 yoke windings. One moves the beam side to side (horizontal ) and the other up and down. (vertical). These go to the specific output circuits. The flyback generates the HV for the second anode, focus and usually the screen. On some hot chassis sets the horizontal output drives the flyback which doubles as the main. Transformer so all the lower voltages are also derived from the flyback. The reason is for voltage control. Only need to regulate the raw b+ which is 130 on most sets. Regulate that and all the others will be correct. On newer sets they used a seperate smps for the lower voltages but the HT, focus and screen b+ which was around 200v always comes from the flyback.
is it high voltage inside like the old tube tv's
Just the 2nd anode like all CRTs
I think the smallest crt were used in some visors on tape video cameras
B/w CRT down to .5" were made for eyepiece. There was a 1.25" beam index color made that used external sensors to syncronize the color circuits. This one is the smallest 3 gun conventional color tube and even though it may have been the pro camera division that designed it camera operators didn't want this because it wasn't sharp enough for critical focusing.
Can it display Doom?

That set's definitely cool :-) ... and it reminds me of my little Sears Binoc TV that I bought new back in 1980... it still works great, too.
No this one doesn't have auto scan. The 3" LCD set I have does
Right on... some years ago I had a little Casio LCD color set ... I remember it only had up/down buttons for tuning and one had to wait for the thing to move along the screen until it locked-on to the next channel ... sure was neat stuff back then :-)
Yes just like my Panasonic LCD. The difference between the casio LCD and Panasonic LCD was casio used a super twist LCD and Panasonic used a TFT LCD which is the same as most TVs use today. Newer high contrast models use IPS screens.
Right on
Hook it to an Atari 2600 and you would be living the dream.
I have the same set and did a repair video on my channel. They make better pictures than what you can show on you tube. The picture just doesn't translate. The cabinets for these sets were horsedung. Most of them are real brittle now, as was mine. Looks like that example was in really good shape. A real cool set for collectors of the micro's and nostalgia. But not something you want to watch for 2 hours, at least I don't being over 50 years of age! LOL!
This one is in my collection now as I had an offer to buy it, and it is in pretty good shape. Yes panasonic plastic was dogshit. Terrible stuff. I remember pulling the back off a 32" TV to service it and it shattered into pieces in my hands. Recycled styrofoam is the joke we used to make about their cabinets.
No, this is not something to be watched, but just for the cool factor to rurn it on once in awhile and admire the technology that went into making a shadow mask tube of that size. Beam index was the norm for small tubes, but this one is the real deal. A shot from it has made it into my updated opening logo.

What’s the Model name? Thanks!

R.I.P. analog tv :(
Miss ya analog tv...... NOT!
@@12voltvids hahaha
Analog tv alive and well at my house. I get 5 channels on the coax here. Mind you i generate them all in the media closet.
Could imagine what this tv cost back in the day
799.95 was the price of this unit in Canada!
@@12voltvids I'm not surprised, the black and white Panasonic pocket TV that looked similar was around $500 in the mid to early 80s
@@12voltvids 😲😲😲😲😲😲😲
I miss the dynamic convergence circuits. This one is probably a delta shadow-mask tube with an in-line gun. Like almost all color computer monitors from the early '80s through the mid '00s except Trinitron and its knock-offs (Mitsubishi Diamondtron and LG Flatron).
Ha! Scott has the service manual. Pause at the specs. The service manual states that it's a 30° deflection angle *in-line* tube! ua-cam.com/video/OoJNqLpPpcc/v-deo.html
Turning 37 in june so of course I like this vid...BBBBOOOOOYYYYYYYAAAAAAHHHHH!!!!!!!
? Ooooooooooooooookay
Ooo so that’s Jerry’s TV
its so cute :3
Im a Fan Of Panasonic Great Company, previously it was National Panasonic.
I found a smaller color viewfinder tube using beam index, trying to find those viewfinders.
I have one of those too but the color filters for the beam detector is missing so it only shows b/w. Beam index is a monochrome tube. 1.25" is big for that. I have a .5 monochrome. This is the smallest color tube, with 3 guns and a shadow mask. Beam index has 1 and no shadow mask so that doesnt count.
@@12voltvids I know it doesn't count lol. I have one of those itty bitty Video8 cameras with a CRT viewfinder, smallest CRT I know of. I am still blown away by the resolution of that thing! I am trying to find a working beam index tube, I want to make a little color travel television!
@@12voltvids are you implying that indextrons are a monochrome television?
@@mandarin1257
They are color only in the respect that they display a color image you could get the same effect if you attached a color stripe filter t ok a black and white screen. Indextron is a type of beam index tube.
They are both a single gun tube but work in totally different ways. In both however it is about timing the beam so that if you want if you want red, the beam is only switched on during the time the beam is passing over the area where the red phosphors or red filter is. In a conventional beam index tube a yellow and blue detector points at the screen (in the viewfinder shell of the camera) so the color sync circuit knows where the beam is. On the Sony indextron version an extra uv stripe is added between the red and green stripes that flashes uv light every time the beam hits it. This strobing uv light it detected by detectors attached to the cell of the crt looking at the back of the screen. This little tv uses a conventional color crt, which had 3 guns, 3 lenses, and a shadow mask. Beam index has none, which means they can be much smaller because there is nothing more in them than a monochrome tube.

I want a scope like that . My next scope will be a tek.
Make circuit of oscilloscope that run on video input composite of TV with out open any tv or any other device.
it make on working tv or video input based devices or monitor but not used A2D based circuit like Arduino or other digital circuit
Useing analoge circuit this is awesome new idea to make every video based devices into oscilloscope.
Can make tow different frequencies horizontal and vertical,and then distrube by injecting measuring signal work oscilloscope.
