It's a blessing to have no audio on a television nowadays.
The president tests negative for a -
Just give me a bangy bang tube please.
Almost an hour in and I forgot what this video started out as.
I don't even bother to watch TV anymore.
Then what do you do if you want to get depressed?@@0tt0z
They always show black people who are barely educated, angry and sad. Thats not the black people you meet in public. Full blown psyop. So gross.
Bent carrot disease, X-rays, lead, mercury, asbestos, and uranium. Your videos never boring! Thanks for posting.
That thumbnail had me cheering for a EOL
I mentally ignored the vid at first
The things you see on ShangoTV. When I was a kid in the 60s we had a couple of those ion chamber meters with the same paperwork and everything. I think they might have come from the Forest Service. I opened them up but, like you, could not make them work. Our family did not have a tradition which included the reading of instructions, so I guess that's why I didn't let it warm up first and it didn't work. It only took 55 years to lay that mystery to rest... thanks Shango.
Tubes were a lot more reliable than their reputation. Shops changed them needlessly because of the 75% markup, and consumers accepted it because they thought of tubes as being like lightbulbs. There were some exceptions. Based on fixing TVs since 1969. I am not surprised that is your first bad tube.
6GH8s never go bad.😂
@insideofmyownmind. That was the exact exception I was thinking of. 60s RCA color sets were full of them and they were always shorted. It used to screw up the color.
Thanks Shango for a great morning interesting the 6T10 tube. great emissions with mechanical failure on one part of tube
those meters have insane resistors in them. The one I have, has resistors with multiplier bands I had never seen before. 220 megohms (red red purple), 2.2 gigohms (red red grey), 22 gigohms (red red white) and then a 220 gig resistor which is two resistors soldered together; one with a single red band and the other unmarked. All are carbon composition resistors that look relatively normal otherwise. It's funny they ran out of multiplier band colours at white. You can see them on the schematic at 31:47 in the lower right corner
You can use a five-stripe code of red-red-black-white-red (🟥🟥⬛⬜ 🟥/2209 2)for 220 GΩ ±2% (other tolerance values are represented with different colors).
Just FYI Shango I look forward to my weekly Saturday coffee with my favorite channel. Love the learning and you very humorous comments too Great laughter too. Agree with you 100%
The thumbnail popped up in my YT feed. Yeah, I know Halloween is coming but this is truly frightening. The woman with snakes coming out of her head.
What a joy to get the sound working just in time to hear Karine Jean-Pierre speak.
The humming is a more accurate representation of her speaking anyhow. At least I can discern information from a buzzing television - its broke.
"The Human Toilet Brush". She cleans up after Biden's messes.
Affirmative action at its worst. The average eye cue (yes, I know) in Haiti is 68.
She truly is a waste of a heartbeat.
"just let me be clear the president has always maintained that our borders are secure". 😅😅😅😅😅😅😅
A friend of mine had a “pit” model. It looked like a very large ball bearing. He claimed to have produced neutrons in his vacuum chamber in an effort to achieve gainful fusion. He passed away from lung cancer a few years back, but probably from too many years in flavor country. RIP DC from C-LAB.
That was very cool watching you hot swap that tube, neat to see how you diagnosed that and then how it reacted as it warmed up. I know that's really simple stuff but it helps people trying to learn....
"he tested negative, he is not experiencing any symptoms" no shit
The close ups on the failed vacuum tube were rather instructive. Great stuff. My dad was a geologist so my brothers and I grew up around rocks like you showed. It was normal to have many boxes of samples stashed all around our house. No way to know what we were exposed to in the freewheeling '60s.
One of my acquaintance wrote his thesis about radioactive building materials. Slag from smelters were used for housing projects in the past. We checked older buildings with a geiger counter. Well, we found some extra warmth in some houses. The residents weren't that concerned... Let's just say the booze worked faster than the radiation... (The radiation was measurable but harmless in all cases.)
I really like the variety in your videos. There is always a ton to learn and be entertained ;)
This is an extensively educational Shango episode. Great exposure to Geiger counters and reference to the other YT site. Budding interests in radioactivity physics and technologies is anticipated.
Loved this video. So many interesting topics rolled into one. A true Shango video
you have to check the front of the screen, the X-ray emissions come from the interaction of high energy electrons and matter, so colliding the beam with phosphors will release X-rays
Folks would tell me as a kid, don't sit too close to the TV. I never listened.
Interesting, I didn't know that aspect of it, only "high voltage in a vacuum".
Yes, I wondered why he was checking the flyback transformer. I was told it was the picture tube that was the problem and I remember that also being discussed on a service technician course for the first iterations of the Macintosh computer (the ones with CRT built in).
@@volvo09 In fact High voltage in vacuum do nothing. You need electron accelerated by that high voltage and dropped against matter (opposite electrode). Thats how roentgen tube works. In TV there are 2 most possible sources - regulator tube, if the direct HV stabilizer is used and CRT, when electrons go against metal mask and metallized surface. Thats why CRT front glass contains lead. But for good X-ray emmition, voltage 40kV and higher is needed, because X-ray photons are high energy ones.
@@xsc1000 ah, thank you... that was interesting.
I didn't know the leaded glass was actually needed, I thought it was in case of malfunction or improper setup.
Long time viewer, first time commenter: What fascinating video. Regarding not detecting any appreciable radiation from the HV section, two thoughts: I do remember reading in some old Mechanix Illustrated/Popular Electronics or similar magazine that the shut regulator triode was the main source of radiation and and almost all of it was emitted in a cone shaped bean out the bottom of the tube. Not an issue if you were watching TV but not good if you were in basement below the TV. If you have a chance, would be interesting to see if you can detect any radiation immediately underneath the HV section of the set. If that's true it was odd the Consumer Reports photo showing the detector near the back of the TV but maybe that was artistic license.
The other thing may be that the X-Rays are relatively low energy due to the 25kv or so HV as you mentioned, so they are not the greatest at penetrating things. Could be the detectors are not very sensitive to those lower energy photos or are even shielded (intentionally or inadvertently) from them.
Regards from Canada!
Never expected to see you here, I have also known of this guy for many years...he finds the best ways to destroy all sorts of unwanted electronics! Looking forward to seeing more of your fine content soon!
@@joshhoman Ha! I find many of shango's very interesting - he a master at it. Many of the TV he does are similar to ones I repaired when I was in high school - the good old days of analog electronics!
There is a canadian guy also doing repairs, whose channel's called 12voltvids and he explained that old professional camcorders' B&W tube viewfinders with not properly adjusted HV thus emmiting X rays killed or caused severe health problems to several TV camera men (probably even drmonstrated it, but I've no desire to look through old videos to put a link here). Potassium iodide might help you only in case the nuke is deffective - large quantities of radioactive strontium are produced in reactors but from a propper bomb explosion where almost all fission and fusion materials undergoes reaction there aren't that much strontium produced as in Chernobyl disaster ;)
He's a good technician but gets so angry about some new electronics, especially TVs, that he gets difficult to listen to. He does some great videos but needs to accept that new televisions are what they are, and complaining will not change that. I'd prefer to be changing a few LEDs than putting a CRT in a 3-year-old RCA color console, which is how I started 50 years ago. The new TVs give consumers more for less money than they ever had before.
I watch shango066 for the social commentary.@@robinsattahip2376
@@robinsattahip2376 12voltvids is an old crab, but that's what makes him so good!
Broken cathode and bentcarrot all in one video. What a cool rock collection.
Awesome work researching the audio tube and discovering the upgraded model.
I like your tangents, always lead to something just as fascinating.
In the ionization chamber the meter is measuring the PLATE current, but it is in the cathode return circuit (B-). The filament connection is after the meter, which never sees the filament current.
That square on the spot weld is a plate of nickel they sandwich between the pin alloy which is a specific type of alloy that expands close to the same rate as glass, allowing it to seal reliably.
But it cannot be spot welded directly to the steel inside the tube, so they use a small plate of nickel to act as a buffer metal that can be spot welded to both the pin and the wire. because the wire cannot be spot welded to the pin directly.
This was a good multi-purpose video with a nice variety of topics, peppered with a little humor. What a treat to play with a Geiger counter! I don’t get much “exposure” to that. Also, I always heard that tvs give off radiation, so it was fulfilling to see that there was none to speak of!
I had the waterfall spectrum up on my SDR zoomed out to show the entire AM band here in the Minneapolis/St.Paul area. Most of the stations fired the test off within ±10 seconds apart from one another. As expected a couple of the foreign language stations didn't participate and never fired off the test. Those stations never ID at the top of hour either. According to a report that was posted on a broadcast engineering site a few days before, 18 minutes after the top of the hour was correct for the phone message, and 20 minutes after the top for the radio/tv message. The news outlets had everyone to believe it was going to all occur at 20 minutes after, so many complained that the phone message was "early".
I guess im not up to date, i had no idea we were supposed to have an alert. I did get the alert but it was a surprise to me.
Great video Shango
Very interesting collection of samples from your mine explorations indeed VERY interesting!!!
Not boring at all. Good stuff too know about, Shango.
I was surrounded by three Verizon devices during that test. Surprisingly enough it was the only time that an emergency alert ever played simultaneously in perfect sync on them.
Very clear sound after replacing that audio tube, nice repair.
Really enjoyed leaning about Television color & AFC
As a (very) general rule: If the needle on any of the Civil Defense radiacs, exclusive of the CDV-700 start to quiver, then you start to worry. If the needle on the CDV-700 pegs at the highest scale & stays there (until the tube saturates, that is), then you start to worry.
This is exclusive of stay-times. Stay-times introduce another level of complexity to radiation exposure.
Cool rock collection! I took a geology class, but we didn't get to see those rocks. I enjoy your videos, Shango! Kudos!
Even though our president can't walk or talk, it was nice to get the sound working again.
The roentgen or röntgen is a legacy unit of measurement for the exposure of X-rays and gamma rays, and is defined as the electric charge freed by such radiation in a specified volume of air divided by the mass of that air.
Those outrageous prices for tubes may be because some sellers of the cheaper tubes want to raise the market price, so they make listings with insane prices and that causes a faster rise in the market price for the tube. So then you can sell it for double the price.
Most intradasting video series on youtube! Keep it up!
Thanks!
Cinnabar (HgS) is also known as the philosopher stone, it is funny, that it can be found in your local mines, whereas middle age alchemists tried to obtain it for hundreds of years))
OREsome rocks dude, Isn't our planet amazing. Love your dark humour as well, keep em coming.
I would love to play around with those detectors like that. Those Western Electric tubes are pretty cool as a source too. Great video.
We would all benefit from that whole organization at the end getting an EOL.
symptoms of radiation injury: baked
that cracked me up
At 100 George Burns was still pretty freaking sound of mind. It's the person not the age.
Great video like the toxic rock collection
"Mild Joe", by Camel! 😅
By coincidence, I have the exact same Geiger Counter as the one pictured in consumer affairs. Works very well.
May be needing soon.....
Uranium ore. Drop it like its hot. Here we have box SQ5 .That gold colored stuff isn't gold but Carnotite, a type of Uranium
ore attached to a piece of sandstone. Shango really knows his ores. Visited enough mines to find those kind of rocks.
Great! Coffee, TV repair & Shango.....
Great content... Especially whole universe of measuring devices that i never knew are in existence... Thank You:) And like allways stay save and effective;d;d;d;d
The Geiger-Muller tube detects ionizing radiation, which, for the most part, consists of massive particles. X-rays and gamma rays on the other hand consist of photons, which are massless and are less likely to ionize the air or gas within the GM tube. Consequently, the Geiger counter is much less sensitive to x-rays. It is likely that the failure to detect x-rays from the high voltage power supply is due to the inherent insensitivity of the GM tube to x-rays. Consumer Reports likely employed a detection method more appropriately sensitive to x-rays = photons.
the scintillation probe didnt catch anything either
Scintillation counters detect ionizing radiation. The point here is that photons (x-rays) do not produce ionization efficiently within the gas within the GM tube. So, one also would not expect significant detection of x-rays using a scintillation counter. See also Scintillation Counter on Wikipedia.
BTW, the reason that particles with mass (electrons, etc.) are more likely to ionize the gas within the GM tube and, hence, result in ionization yielding a Geiger count is that particles with mass decrease in speed as they lose energy as they pass through matter, including through the gas within the GM tube. As the particle slows down, the so-called capture cross section of targets within the gas increases. As the capture cross sections increase, the likelihood of the particle being captured and suddenly dumping all of its remaining energy into and ionizing the target increases suddenly and dramatically. The result is that most of the energy of the incoming particle results in capture by and ionization of a molecule within the gas along the path of the incoming partcle. This, of course, marks the beginning of the cascade that yields the Geiger "count." For more on this phenomenon, see Bragg Peak on Wikipedia.
On the other hand, photons (x-rays and gamma rays) move at the speed of light and their speed cannot be reduced below the speed of light. You can't catch a photon and bring it to rest on your desk top. So, the photon's capture cross section does not increase as it passes through the GM tube. Consequently, its probability of being captured is uniform along its entire length of travel through the tube, as opposed to most of its energy being dumped at a discrete point along the path of travel. For this reason, photons are much less likely to result in ionization and, hence, are less likely to be counted by any detection method that relies upon ionization.
@@spondulix99 I doubt Consumer Reports used anything special for their test. Maybe it was all fake
@@shango066 The physics I know. What Consumer Reports did, I have no idea. I note that CR failed to report what instrument was used to make the x-ray measurements and also failed to report quantitative results.
BTW, the same physics comes into play crucially in the irradiation of malignant tumors. If you ever require such treatment, photon therapy, such as with Cobalt-60 gamma rays, is generally to be avoided, and charged particle beams are to be preferred. The heavier the particle, the better. I can explain in more detail but, perhaps, this is not the proper venue within which to do so.
That piece of uranium ore has one side apparently sprinkled with yellowcake, which is a more-concentrated form of uranium. I'm sure it's non-carcinogenic if you don't spend too much time around it, though.
That is carnotite most likely, a uranium ore. Yellowcake is a processed form and doesn’t occur in nature.
I really miss the good old days when you could fix your TV by smacking it with a screw driver. Percussive maintenance.
Glad we only get a text message here in Australia in emergency broadcast.
Dan, if you want to test something convenient take the cover off of a smoke detector and where the metal chamber is is the ionizer. There is a little piece of uranium to pretest for smoke built inside. You can point the Geiger tester at the little dot on the circuit board inside the metal ionizer cabinet and it should send your Geiger counter stupid if you can get close enough to it it might even read 1/4 scale. 🎉
Americium, not uranium.
@36 minutes Shango066 old luminous watches are very radioactive the numbers and hands will give a good reading on the Geiger counter!
The cathode connection that was the failure point in that one Sylvania made tube around 17:50 couldn't have been 'hanging mid-air' inside a vacuum tube. 😏
Zentihs used to go thru 6G10's at a pretty good rate as well.
I have AT&T and the EAS test toned out as 2:18 local time, two minutes early. Posted a video for it. Take care.
Sorry if I come across as argumentative, but "local time" doesn't mean much if we don't know where the hell you are ;-)
Xrays could start even at 16KV. The 6BK4 shunt regulators were the major Xray concerns of the time. Xrays are not same as Gamma rays or other radioactive decay, and a sensitive detector could be triggered by unrelated interference such as HO tube spikes. Color CRT at 25KV were eventually made of lead doped glass to shield Xrays exiting but the front face could not be heavily doped without blocking light as well, and CRTs of the roundie era were dim to begin with.
If the time should ever come Shango, "Can I have some of your purple berries?" It's a song lyric, for those who don't know. 😁

I've been eating them for a while now... It/they seem to help with.... My memory tarries off from there. I was a teenager in the mid 1980's and I loved classic rock and psychedelic music. And pop music. I should go back and listen to some of it. Later today maybe. I plan to change out my daily driver workhorse receiver with another no frills more modern surround sound receiver I was given. It has output for my powered sub-woofer that I bought many years ago and never implemented.
Almost Cut My Hair came to mind... That's not it. So I looked here and listen to Almost Cut My Hair and then looked a little further....
Wooden Ships! Just fantastic!
Say can I have some of your purple berries? Yes, I've been eating them for several weeks now... Haven't gotten sick once....
A half century later and look where we are. On the abyss of WWIII and being manipulated and destroyed by a small class of nasty and wicked people. Things must change. Awareness is a prerequisite to averting disaster and freeing humanity to excel to it's highest ability.
Some xrays come off the HV rectifier tube. Any time a high energy electron suddenly stops you get radiation. In the HV rectifier it is when the fast moving electrons from the cathode slam into the anode. In the color TV shunt regulator same thing. Or electrons from the CRT cathode hit the phosphor. Higher the voltage, higher the energy of the radiation.
I’ve enjoyed watching this project. As a very young boy, I have memories of watching my dad repair the larger PB b&w set in our living room. We had a smaller Zenith b&w set as well. Dad knew tube electronics and always liked Zenith, that’s all he’d have after the experiences with the PB. Did you know there is a risk permanent CRT damage by displaying little Ms Diversity Hire?
She's such a disaster. And that hair...
I Smashed it at 1k. Likes.!!!! You are the man!!!
The Geiger counters and the rock collection was interesting. I didn't know it was possible to order it through the mail.
The EHT shunt stabiliser (stabilizer) would emit a lot more in the way of xrays with the brightness control turned all the way down. It'll be passing all of the EHT current in that mode.
My parents had one of these when I was a kid. The sound constantly went out on it along with flyback. They got tired of repairing it all of the time and replaced it with a Panasonic which ran for twelve years without any problems.
That set is doing great. Makes me wonder just how many hours some of these old sets have when the tubes are covered in tungsten evaporation... looks like it would be near 20k hours.
(At least this time the voice message was clear and audible unlike the test we had a decade ago.) I wonder if the delay is because each station monitors another just like the old EBS system. In that system, each station was "daisy chained" to pass on the alert like the game of telephone we all played in grade school. PS. Gone are the days of the official pink sealed envelope on the studio wall with "authenticator words" inside that you had to VERIFY first against the AP or UPI teletype machine printout before you ever transmitted the message over the air. That simple check was essential to stop an alert that was rogue, presumably initiated by enemies. Today, the system is completely automatic because most broadcast stations are just a computer in a closet.
That is exactly how it works. there are a few stations that are what are called PrimaryEntryPoints and all stations monitor that one. I have a recording of a few of these tests and what's interesting about all of them whether they be TV or radio, they all monitor AM radio. and the further down the chain they are (since they can monitor a secondary entry if they don't hear a primary) it just gets further in the noise just like a VHS tape generation copy. Daisy chaining allows very good reliability in a emergency scenario, but not intelligibility
yeah i remember when we used radiation meter in the TV repair in the 90s for big screen tvs like sony philips toshiba
Meter on first unit/schematic was measuring cathode current not filament current.
Wow! That radiation detection part should be a separate video. Just so people can reference it. Because i saw a guy on a video arcade forum someplace giving people crap for restoring arcade game monitors saying they were radioactive and… I thought… how can that be? Now i know that guy is full of it! 😮
All interesting stuff ! Our National test we're not on time in the mid west, yeah I'm thinking it was a "different kind of test" .
A GM meter reads a much lower rad level then a high level area that is designed to get the post attack background level.
Started the X-ray scare and lead poured into everything
55:50 if I read that right it said .03 mr/hr at x1000 is 30mr/hr that seems to convert to 4 chest xrays exposure in one hour.
Shango,everything is insane now.Mike the Greek
I have the external probe GC and remember when I bought it, it was supposed to be better than the internal probe one.
Nice rock collection my daughter has a meteorite that is radioactive. Fun stuff.
When I was in tech school in the early 80's my teacher was in college taking courses and he wanted to do the experiment you are doing looking for Xrays from a TV to see if there were any to be detected and he was able to obtain an Xray detecting meter and we did the same thing you did all around the shunt regulator tube and rectifier on an old Zenith hybrid set-what we discovered was there was nothing around the rectifier and shunt tube but there was detectable Xrays right in front of the picture at the bottom center of the picture tube-so kids laying on the floor watching saturday morning cartoons were getting the bulk of the radiation
The ppl that try price gouging on tubes, I scroll right past them..!!
They think they've cornered the market and no one else has that tube available.
6JE6 is ridiculous price wise..!!
Get down with Rebelsis!! 😂 Might I offer a humble addition to your other comment about president tests negative? President test Negative for mental acuity.
Looks like the weld might have been a little hot on the cathode of the failed tube.
actually the smoke alarms DO still have AM241 in them the thing is AM241 is mostly an alpha emitter which the metal can of the source shields it i have 2 counters 1 is alpha beta gamma the other is beta gamma only and if i remove the lid on the can in my detector the alpha detector gets almost 60,000 counts per min while the beta gamma gets a few hundred
I was under the impression that the CRT is what emits X-rays, and has to do with the electron velocity (hence why it is associated with the higher voltage in color sets). The CRT glass is leaded or boron or something to prevent the X-ray emission. I did not read about this prior to making this comment, so I could be totally wrong!
When I was 12 yrs. old the TV technician in our town told my parents not to let us kids lay down in front of the color set ( roundie ) with our feet under the set . He said the X-Rays would come from the shadow mask and downwards . Probably all directions if it was the electron stream hitting the shadow mask . I would think the picture glass would have stopped any X-Rays any way . If any existed at all it would be very soft X-Rays . In High School I did a science project putting dental X- Ray film all around the set for 4 weeks . Not one of the films showed any fogging what so ever . Our town dentist developed the films and " read " them . I know some very early color set HV rectifier tubes had problems with X-Ray emissions but the glass was changed to leaded glass to stop the radiation . Your results were the same as mine back in 1970 in High School Science class . No X- Rays . I got a 1 uCurie test disk back in 1969 and it still puts out a good test signal like your test section does . I think we were all still in the Atomic Mania phase back then and every science fiction movie had Atomic Monsters etc.. I worked in a lab some in later years and we knew for certain if the source produced any thing or not and how much . I do not know , but I suspect hype seems to play a part in all this historically . A good , decent and dependable Geiger Counter removes all doubt though . I must say it was great fun to check it out though back then . Your video brought back some really great memories and past results from a long past science experiment .
Awesome.
Only 3:48 in, and already a Super Cut :)
I think the 6AD10 sounds better than the 6T10, still have to clean up that filter though
TVs were EXPENSIVE then. $600 in 1968 is over $5200 today.
32:29 taking a chance commenting at this moment with out watching all of it. I had one of those survey meters. from what I read the lowest reading on that meter is very unhealthy and in most cases you will get no reading at all unless there is something VERY radioactive nearby. the one I had, had an extension of the ionization chamber that you could leave outside your shelter and get readings without going outside. if you can zero it, it is working.
In Afghanistan, there were mountain ridges covered with the bright yellow Uranium ore. You could see it miles away.
I like the ore collection
I think this is the first time I’ve seen one of your videos on the UA-cam landing page. I’ve never seen that before. They have always been relegated to the post-video recommendations after watching something else, or I always have to search for your channel manually.
I saw an earlier date stamped in red right above the June 1977 date. The latter date must have been its last test date. The machines are clearly older.
The alert went two minutes early on T Mobile for me in the Midwest US.
Hey Shango, I would love to see a video where you fix that ion chamber meter. I have one very similar to that and mine doesn't work either. Mine moves the needle, but it just pegs all the time no matter what setting its on.
I agree with you about the test it lasted only seconds instead of a minute on my phone and the sirens went off in my town twice but only for a about 20 to 30 seconds each. I heard the tests was supposed to last 30 minutes. I actually turned off my phone but I heard everyone else's phone go off at work.
i had what looks like a new ECL86/6BM8 develop a short between grid and cathode of the triode section, nothing to lose i blasted it with mains via a 40w bulb, so far it seems to have cured it ! also come across some 'new' production Edicron branded EL84/6BQ5s , 2 of them with what looks like tiny metal particles loose in them, they have the etched philips mullard type code near the base, and according to that made by Ei in Yugoslavia ... i've come across a few broken cathode connections in 'used' american type valves but not yet in any british/european ones 😉
