If there are any other GEs like this one left, they won't likely be in as good of shape as this one is.

He lucked out. It's good he's using it outside not just for safety reasons, but the digital signals come in well. Not a bad picture for a 57 year old set.
I have one of these in a slightly different cabinet. I got it back around 2014 and had it shipped to me through someone on Uship.. The CRT is pretty much dead.. I didn't know these were super rare.. I'll make sure to hold on to mine..
Agreed! If there's more than one left, the total might be like 5 in the entire country. And this one is in *damn* fine condition -- easily the best of the very small group. Assuming there's even a group. Very much worth saving!
As an aging TV engineer my brain is triggered to smell dust and ozone whenever I see the insides of an old TV set. Considering that set is 57 years old it's amazing, even if it is a crusty old GEC cost cutter special. I think I heard Bob Anderson scream when you threw that tuner lid in the garbage.
Why'd he do that? He didn't say.
Started my TV repair career and in 1974. Worked on quite a few of these. Did a couple CRT replacements too in these. Those buggers were heavy…..
I started in 69 and hated them, for one thing, we never had the tubes in stock and they would not work with the RCA test jig so you have to mess with the chassis in the set. No access from the bottom, of course. GE sucked, but then so did their radios.
@@robinsattahip2376 In our area in Michigan, Zenith and RCA was the most prevalent brands. Once the K-mart type stores started selling TV’s, I started seeing lots of other brands.
In 1972 I replaced the flyback in one like this, I was 15 years old then. My grandfather was a GE repairman so I got help from him over the phone.
GE 1967 KE chassis, my parents are still alive and it sits downstairs in their basement. Main power supply short, burnt out line filter inductors, and cataract on the 23" rectangular tube. Never been really interested in getting it going since I don't want to deal with the cataract removal. Was $700 new, which was not cheap back then, which was probably two months pay for a blue collar factory worker at the time.
@@zulumax1 Cool! Did your grandpa work for an authorized GE shop?
They sure were expensive. Think what kind of a TV $700 could get ya today!
At least a 65” that’s hundred times better!
The highest failure part replaced on these were the plastic gears in the fine tuning inside the tuner. Lots of house calls for replacing those. My grandfather, GE repairman, would always keep a good stock of those on hand.
The tuner shield literally going straight into the garbage, was fin' hysterical.
Nice.
Cleaned hundreds of those mechanical tuners like this. The cover did have an effect on interference so replacing it was standard procedure. Gotta admit I did leave a couple off when I couldn’t see too well in a customer home!
That was funny, I imagine someone thought that was real and not a joke
It wasn’t uncommon to come across a TV without the tunner cover on it. Some of those were tough to put back….
@@user-pq9ji7kt4l that was the joke, in older videos he always got mad when he came across a tuner with a missing shield, why would he toss it if it made him mad?
car mechanics when they see a splash shield
"The first thing you wanna do....is throw this away.... *tink*...slam!" After doing TV repair in the 70's and 80's, I love it!
Refreshing roundie and tubes edition. My favorite genre. Definitely would restore. Nice look and unique place in the vintage televisions universe.
Like watching TV through a port hole.
I think that was you speeding past me the other day!!!! 🙂 Robert, San Diego
GE was not a house brand of ours, so we weren't overly versed in them. But the first, last, and ONLY example of *THAT* particular roundie came in for service. No color sync. It turned out to be that damn NE-2 neon bulb, even though it was lighting normally. Replaced the bulb, and problem fixed(!). Figgered the bulb must have to do with burst gating.
lol. Never would guessed that was the problem….. interesting fix.
Yeah, when I first saw it in the beginning of the vid, I wondered if it COULD BE the one with the crazy-ass neon bulb. And it was! Only one I ever seen in 35 years in the trade. Shango musta got its twin.
Mother: DONT PLAY WITH THE BUTTONS
the tv repairman to repair the tv when no one is looking: 24:03
Dang, I used to use the same CRT tester!
Amazing how zapping the CRT guns could give it a little longer life.
He did not rejuvenenate it, and that would make a good tube worse. Good call letting it run for a while first.
He didn't, thats the point of going up slowly in bulb sizes. Rejuvenation gives short lived benefits
Nice find, that set is in great shape. Can't wait to see what it looks like with good color and a full setup.
I like the cabinet and speaker cloth.
It's hard to believe the TV is so old with those components looking so new (under the layer of dust). Looking forward to part 2!
You're right about the light bulb being current limiting. Although there's another useful aspect to light bulbs here; When the bulb is cold it will have much less resistance. So it sort of works like a soft-breaker. When something shorts the light bulb will heat up and limit the current to a low value. But when it's not shorted, the cold light bulb will allow more current.
use a 110v bulb in a 220v country and the bulb is now also a fuse when something shorts.
I use an old 750 watt camera light and veriac and outlet box with on off switch. I dont do near as many resurrection/restorations so let her rip and ill fix it if it shorts.
A variac has some degree of current limiting ability since the transformer will saturate on high loads, but it's a voltage source where a light bulb is just a series resistor that will drop more voltage if the current becomes larger.
Shango, thanks for teaching us novices at electronics the difference between a variac and light bulb limiter. I’ve been watching tons of electronics videos and this is the first one I’ve seen where the host thought to mention exactly why one would use either. Thanks for being a great teacher. It’s why I’ve been a subscriber of yours for years.
Oh and one more thing, my parents had two of those GE Performance TV's and I'd say theirs were somewhere from 1978-1981 models, they had a 19 inch color for their bedroom and we had a 13 inch color in the kitchen, both were those performance tv's. Both of those TV's lasted many years. I'm pretty sure that 19 inch was a 1978 model because we got it when we moved in the house and of course that was a '78. They had that damn TV forever. It had a good picture and worked well until it just didn't one day. I think it croaked in '98-99 or somewhere so they got 20 years out of it.
I found an ad for this set or a similar one December 1966 and it was the cheapest color set in the circular; $299. The next cheapest color console was a 19" rectangular RCA Victor that was $389. The only other color roundie was a Zenith at $399. It's a PDF or I would try to post it here.
I did TV repair in the last half of the 60's. That Zenith roundie was a very good set. This GE with it's Compactrons is a cheap relic of the declining days of tube electronics. But it is in nice shape. Take care of it.
@@scottmorton1202 I think that was the downfall of GE; they were reverse engineering their products to a price point and your repair experience would indicate they were good at it! You paid less and you got less.
man loves to bring stuff up all soft and delicate with a light bulb...off camera he has a bag of marshmallows in his hand when it catches fire..pure entertainment 🎉
I just love this set, please return to it if possible! As usual a big thank You for sharing your adventures in the good old stuff.
Wow, thanks for the blast from the past! I was ~13 years old and already an experienced tube jockey keeping the color circuit working on a slightly older model of that same beast to watch the very first episode of Star Trek TOS. It lasted almost 15 years total and was still "working" when it was finally "retired"!
I had it hooked up to an Ampex 7000 series 1" video recorder (mounted on a Flowtron) in the early 1970's. I used a Sony 1600 tuner and it's color processing to record and play in color. Wish I had a picture of the setup and that meatgrinder head drum fan blade.
They had a super nice d-i-y skate park under a freeway overpass in Atlanta, adding structural integrity to it and everything! Then the huge pallet hoard next to it caught on fire and they blamed the skaters, not the hobo culprits, and demolished the park.
You're being too nice by calling the bums hobos.
Of course the dang skaters get blamed for everything….
One of my favorite looking sets...both inside & out
Great video, as always.
ഈ TV യും വാങ്ങി ആദ്യമായി ചിത്രം കണ്ട ഒരു ദിവസം ഉണ്ടായിക്കാണും അന്ന് ആ കുടുംബം എന്ത് മാത്രം സന്തോഷിച്ചിരിക്കും
The Goodyear blimp was on its way to watch the fires burn up the freeway in San Francisco. It’s own sort of EOL video. 😂
Shango is the type of guy to floor it in the left lane
You can't get a ticket for impeding traffic if you're continuously passing everyone else at 100 mph 😅
Thank You for all your hard work making these videos from Ireland 🙂🇮🇪☘️
I agree it is worth further repair as it in great condition for almost 60yrs old and rare. one of a kind. Thanks Shango great saturday morning fun
Didn't realize these were like hens teeth.. very interesting and intriguing!!!
As always, super well done! This is 'must-see TV' for me...
We had a GE COLOR tv for 1967 not a roundie with a pull down channel mechanism tuner. Loved that TV but you are right. We always had breakdowns on that set. I still miss that tv. It had a beautiful color picture. I was a kid then.
Our first color tv was a roundie. Philco Ford. All tubes that I know of.
Interesting video!
I remember, in the sixties, my parents buying our first RCA color TV. It looked pretty much like that one and came with a free RCA clock radio, which they gave to me so, I could wake up for school.
A friend of mine at work calls GE "Generous Electric." Nice set, nice video, very enjoyable!
Yes, I enjoyed another good video! Thanks for taking the time to do it.
RIP pallets. They haven’t found the root cause of the fire, I wood say they’re stumped.
That would require the libtards to admit leaving homeless under the freeway to burn pallets is a bad idea.
Awesome set very cool I have learned to love the old roundie sets looking forward to future videos on this set very cool set love it!!
Love your road trip videos! General Electric (and other makes like Motorola,) would often brag about the quality,and sometimes even the maker of their cabinets. The consoles were considered furniture. I have the General Electric console stereo you see in the later episodes of "Leave it to Beaver" and it has a tag stating that the cabinet was hand crafted by William Tell woodworkers of the finest hardwoods. It also has General Electrics "Vacu-Magic" tone arm that has a vacuum nozzle and hose built into the tone arm! The idea was that it would suck the dust off the record as it played. When i bought it the vacuum motor was seized but i repaired it.
Motorola was legendary for the quality of their cabinets, considered very fine furniture. Don't know anything about GE, but this cabinet - even on video - looks like crap. Seems the finish is disintegrating - from age - and not from abuse.
*WAS IT WHISPER QUIET* ?!?!?!
@@godfreypoon5148Yes,it is
The vacuum nozzle is under the front of the headshell,there's a clear ribbed hose that runs under the tone arm and down into the console. The hose enters a beehive shaped dome inside one of the speaker baffles and the motor is inside there. I believe GE only made the vacu-magic one year. The same changer was used in their top of the line metal "trimline" portable stereos that year too,same exact tone arm,but it didn't have the vacu-magic emblem or the nozzle,hose,etc. Only the console got that.
@ericruud9328In reality it didn't actually do much and I believe they only offered the Vacu-magic for one year. I think it's cool though. It comes from a time where designers and engineers minds were allowed to run wild and manufacturers were looking for futuristic amazing new options to entice customers with.
@KameraShy Yes,Motorola has some console cabinets designed and built by Drexel. The earlier,higher end Ge's had the nicer cabinets
Now THIS is what shango is all about, love the road trip pickup videos, thanks for posting mate, just lying in bed all snuggled up watching this on my iPad. i think your last roadtrip video was about 6 years ago.
Have you ever tried fitting a rectangular CRT in a roundie set? the shape of the surround around the CRT looks like it could be a perfect fit if you dremeled the plastic out where its dark grey.
And shango just a heads up
A friend of mine has that exact cheap radio in his caravan, the damn thing caught on fire!
But you also have to modify deflection circuit to add pincushion correction.
Hey Shango. Last road trip I can remember was with Chris and you went to an estate sale from a television technician guy's house anyway thanks for the video Shango thumbs up as always
External tinted safety glass is missing is why no cataract. They did not use a bonded safety glass tube in this chassis . GE had the coax connector going way back. I have owned multiple versions of it and I’ve never had many issues with them. I still have one awaiting a recap, but it works quite well unrestored.
Exactly my experience. I probably have almost a dozen and they work well. Filters are a little esr ripple-y...
Thoroughly enjoyed this one. I thought we were watching an episode of Most Extreme Elimination for a second near the end of the video.

Last week I drove about 100 miles for 2 sets, $45 each. A rca ctc 38 hybrid rectangular set, and a dumont roundie. The dumont has a lot of hours on it, both the tube and the flyback have been changed, however the rca looks to be low hour. They both have good testing tubes thankfully
ten gallon pat
Lucky dog. I hope you'll do a quick video.
I love General Electric TVs and stereos I live not far away from where they manufactured the TVs and my General Electric 17” b/w portable came from a guy who worked for GE at the time and lived in the suburbs right outside the TV plant (now Lockheed Martin). He bought the set at the “GE store” which was General Electric’s in house store at the factories for GE employees.
(@34:09) Yeah, X19 is probably a varactor diode, as the anode goes to ground, and the capacitance was controlled by the reverse-bias voltage on the cathode (here, labeled “97” on the schematic.)
The notation "AFC" next to it is a pretty good hint. ;)
Thank you for the quick cutaway to the Goodyear flying phallus, always nice to see 😂😂
I use a VARIAC with a modified kill-a-watt to act as a voltage, wattage and current meter. I take note of the power consumption of the set, and if it reaches that value at an input AC line voltage of less than 117V, I turn the set off to investigate a possible short. Monitoring current and voltage carefully is the key to successfully using a VARIAC versus a light bulb.
To save all that use a bulb....life's too short.
@@andymouse I used a series bulb years ago before I got my VARIAC. I wouldn't go back to it though. I like to be able to precisely dial in the input AC voltage and monitor current and wattage at the same time. Cheers!
:)@@crooner2007
@@andymouse ideally you'd want a contraption like the one Mr. Carlson uses on his channel. It combines a VARIAC along with a anmmeter and a light bulb used as a current limiter. Cheers!
Dude...
Not cutting on your skills. But, old timers like me cut our teeth on sets like these. Your repair style had me in stitches. LOL
I've seen the fire on UA-cam news... last week,but i didn't know they did store pallets under the freeway... I'm looking forward for the next video 👍
wow color in 1966
Obviously that was before your time.
How Cool! I never knew those CRT's were called "Roundys". Makes sense though. I remember watching my "RICH" Aunt's roundy TV in 1965 when COLOR was REALLY THE THING! I certainly noticed those "ROUND" corners too. This set looks just like one that Samantha had in her living room.
Banging on the side of the set usually does the trick. Hey, hey, hey, Newsomes burnin down the house!
This is rare and the flyback was literally discontinued as of April 1988. The set was rare and the flyback on that set was also used in the 1967 variant. The 1967 variant didn't need the flyback for working IF but the 1966 version did. Pretty crazy. I have that same set. Absolutely no wax left on the flyback but it's still good the horizontal oscillator coil is gone. Crt is really strong still but bad cataracts. That set used either 21FJP22 or 25AP22 so this set they made a non roundie version.
The 23:12 part was the best part in this video!
They also stored hand sanitizer under the bridge.
That's a beauty. What's funny is GE might not have manufactured good sets, but they owned TV stations, and for many years owned NBC.
We use light bulbs when we build and service FPV drones. Like a 12 volt 1157 tail light bulb. If the drone is shorted, the bulb lights up. We call em "Smoke stoppers"
It's saved my stuff more than one time. Meanwhile I know guys who were too lazy to make one, and their drones go POOF because they didn't solder something correctly.
I was just a young teenager trying to figure out car stereo wiring and had the light bulb go off in my head and used one for many activities.
If you have a blown fuse in an automobile or truck it's natural to replace it. If it blows again I always go in with a headlamp instead of another fuse or circuit breaker. I can wiggle or disconnect things to see if the short goes away or use a compass or DC current hook probe to trace the circuit. If a new fuse or automatically resetting circuit breaker is used it can blow open the short and possibly prevent it's discovery until another point in time when the failure recurs or possible damage or fire result.
When neon bulbs are used as regulators, they should be illuminated, because when they're in darkness there's nothing to ionize the neon. That's why they're usually next to the pilot light.
There have been a few tests of voltage regulator tubes and some of the tubes took up to 30 seconds to strike when in total darkness. They can strike anyway by cosmic rays and radiation. This is not unlike how some geiger tubes operate.
Didn't they also use neon bulbs for relaxation oscillators to generate sawtooth waves? I suppose if such a bulb were affected by the light in its environment, the amplitude of the sawtooth would also be, so a trigger diode would probably do a better job.
Conduction current of small neon bulbs (like NE-2) is too small to be useful for shunt regulation (except maybe in some *very* high impedance circuit). To be useful, shunt current has to equal a signifigant percentage of the load current.
Q nå
Incandescent bulbs are used in Wien Bridge oscillators as part of the feedback in order to get very low distortion sine waves, I know that much cos I just built one but I'm sure your right !@@pcno2832
I remember very well one day I went for a Philips TV set, European style (screen leaning out, not into a frame as US tv sets). Well, I arrrived in a gypsy neighborhood, they were bungalow houses but there was no furniture, only mattresses, I remember. They are not neighborhoods like you would go alone.
Greetings from 🇨🇱
Wow, that was a treat. I haven't seen a CRT TV that works in years. The colour looks fine to me. Perhaps just replace the valves and the capacitors and that old TV set should easily last you another hundred years.
Thanks!
I wish I could find color roundies locally. They all seem to be out west
I remember working on those, I had a GE Porta Color I found in the trash, the blue was out, I worked in a shop, so I was able to replace the tube. It seemed the the blue gun failure was a normal occurrence on GE TV's
I ran across one of these once - the buyers of an abandoned house were selling it in 2009. The hipsters were insistent on $150 and wouldn't let me hook a crt tester to it. It did turn on but the crt looked tired. Probably became a wet bar in that neighborhood...
I love it and want it!!! Lol😂 Now to watch the video. Unique color oscillator circuits as I recall...
2:22 Colonial style cabinet. Every old GE set I get works!
Nice healty tube
what an interesting and unique set...That color demoduation circuit looks interesting, i wonder if other sets of that time used it.
I doubt it... seems like something GE whipped up themselves, and probably patented, to avoid RCA copyrights.
yep, definitely, a bulb is better than a variac in most cases, ideal is probably both, variac first , then feeding out through a bulb
It'd be nice to see such an obscure piece be tuned up.
I do remember somebody on VK years back mention that GE sets will pull the nails out of the walls haha I have never forgotten that for some reason. Do you remember when someone said that?
I'm English and amazed at the design of the 60s American TVs and especially the ones that have delusions of being furniture. The trim on the top of this is rather odd to me. The colour might be whacked but the definition and clarity is excellent.. Thanks for the look at this.
Besides repairing skills, I can hear you have great taste for music, House Music !
My uncle brought us a 12 inch b&w GE set in the early 70s for 100 bucks. He also bought a 10 inch color for 300. Both were reliable but used compactrons, both blurry as in low resolution too wide with no adjustments, you had to overscan the vertical to make the geometry right. Just cheap sets that that the Japanese could easily blow away but my uncle was a made in America person.
Even though this was one of teh cheaper made and lower quality sets from back in the day, I doubt any of the modern stuff would hold up like this has. I don't think 50 years from now there will be guys making videos repairing old LG OLEDs like you can with these old CRTs.
I HAD ONE OF THESE EXACTLY LIKE THIS ONE
yay saturday night shango!!!!!!!
Cali ramps and overpasses look like they're ready to tip over in an earthquake with the slightest seismic shift. Ohio uses three humongous pillars on their ramps and bridges and I've experienced two small tremors here in 40 years.
I love shango066 channel
".....Come to flavor Country!..." LMAO!
Man that’s in nice shape! I wonder if they made round tube sets that late in the game just to use up old stock and sell it off at a bargain price or if there were actually some people who preferred a round CRT over rectangular. 1966-‘67 is pretty late for a roundy.
Made in nearby to me "Sorryexcuse", NY...
Electronics Parkway in Syracuse, NY. It was Martin Marietta last time I drove by. I had worked at New Venture Gear and understand that is no longer there... 😢
@@johnnytacokleinschmidt515 Yup. New Venture Gear closed around 2012. Martin Marietta became Lockheed Martin and is still there.
I have a 1966 GE PortaColor and I think it's got the same tuning knobs and dials as this one.
I have been using both bulb and variac
Yeahhh new video✌️
1N636 is a germanium diode. The diode itself might not be too critical, but having all be of the same type might be important.
Great tv
A light bulb can be seen as a fast acting positive temperature coefficient (PTC) thermistor in this setup.
nice cabinet on this one. sparko twerkulate it. it reminds me of watching Speed Racer at a Babysitter's after K
By the color bars it looks like problem with G-Y signal. So color demodulator is OK, but color matrix after them works wrong. Thats why there is no green color, but there is no problem with color balance set up - white, grays and black are OK.
I look at alot of videos of abandoned homes and see quite a bit of vintage electronics very interesting. You will be surprised what is still in attics and basements of old homes. I watched two videos alone today p*** video head to Vintage black and white TV sets one set was a 1953 Magnavox have the other was a 1961 zenith. In another video recorded by the same Explorer and a different house had a wind-up gramophone in the Attic as we all know francophones are worth quite a bit of money.
I would love to have a roundie for a daily in my house and here in Vegas it would last forever.
interesting tv, I thought most or all roundies were black and white, that's cool they made some color tubes as well
From 1953 till mid 60s all color TV sets used round CRT.
Humidity sucks i'm north of Chiraq and let stuff sit in my basement for a month sometimes b4 i touch it or bake it in the sun with the cover off.
I think that’s a early American style cabinet
Wow, pretty uncommon on this channel for a roundie to just...work, well kind of. It's watchable right out of the truck.
Asking to relocate the pallet yard probably was going to offend someone.
The flyback had two meltdowns we then gave up on it.
Even though I grew up on this tech and even fixed a few there's a side of me that thinks of it as completely r-word today. It still seems like a fluke in the space time continuum that they even worked at all. That said, we all still use technology that is even older every time we fire up an analog radio, including an analog stereo receiver. That format is still in wide use almost everywhere in the world in 2023. This set is a great specimen I'm sure you will get it to it's OG glory.
hey..thats tha tv i watched mr rogers on....
I'm surprised after all these TVs you don't have a mirror sitting around for adjustments!
