Crazy how old school TVs picture was one unit like at a time, our eyes are so slow compared to electronics

A friend and I used to haunt the local dump looking for old TVs so we could pull out the flybacks - carefully discharging picture tubes first! We hooked them up to transistor driven multivibrators and even with a 9-volt input could produce a surprise shock. We sold them to other people for $10 a unit and never thought of killing someone or getting sued. The '60s were a fun time to be alive.

Many young would-be TV repairmen like me got their first big shock from a system that was not discharged. We learned about high voltage capacitive discharge real fast.

I was a TV repairman during the CRT era. I got shocked a few times, but learned quickly to carefully discharge the CRT with insulated tools.

I remember as a teenager seeing the spark from an arcing flyback on an otherwise very nice discarded TV.
Slathering clear silicone RTV with the unit off, and letting it cure for days solved the problem. I was able to enjoy that TV for many years.

I still remember the particular scent when a flyback had recently shorted.

I did my apprenticeship in the 70's at a television factory and my job for 3 months was winding LOPTs, I was so sick of winding them that I was so over the moon to be moved to alignment for my next 3 month stint.

The final anode voltage could give a 'very nasty bite' but the delivered current was low. Fatalities were rare.  The earliest CRT TV sets with mains-derived EHT were truly lethal, often called 'widow makers'.

I remember when I was a kid in the 1950s I mess around a lot with electronics especially TVs which I repaired for neighbors and my little pinky touched that high-voltage wire and that I actually threw the thing across the room has scared me so much 20,000 V burned a hole in my finger

There was a third option for providing the extra high tension supply to television cathode ray tubes. This used an internal high frequency oscillator in the set, a step-up transformer and a rectifier. The system was used occasionally in British receivers of the 1950s (Ultra Electric) and also Continental colour sets in the late 1960s (Tandberg). By separating the line scanning circuitry from the E.H.T. supply, better regulation of the latter was provided. This was important when the picture changed from full brightness to a dark screen.

Old monochrome CRT monitors existed for computers but they were known for burning in.  I don't know how many of those old ones there are still left

Not only was the CRT TV cool. It was REALLY cool, when the Emerson, color, 5 inch portable TV 📺, AM/FM radio (for example, and MANY, MANY more portable TV'S came about, too) came out. I got the Emerson for Christmas 🎄 of 1984. I REALLY liked 👍 it, because I could go to my bedroom (or anywhere about the house), and plug it in, and watch it!! It also ran on 9 "D" size batteries 🔋, but that's so expensive. It was so exciting!! The picture on the screen, and the fact that a CRT TV 📺 could be so small!! I could always flip the switch, and listen to radio!! This was about the best (and nicest) TV I've ever had!! It, however, did not come in cheap. This Emerson, AM/FM radio, costed my parents about $500. I owned this TV for a period of years, before I sold it at a pawn shop. They only gave me $5. I probably could have sold it for at least $200, on the street. Not only did TV's shrink from floor models, to a portable 5 inch TV. After that, they became handheld units. I asked for one in 1984, but my parents got me the Emerson instead. A period of years later, I bought a handheld PocketVision 22, with AM/FM radio, from Radio Shack, in 1989. It costed me about $221. It was an LCD (Liquid Crystal Display), TV. Batteries weren't to expensive, using only two or three "AA" size batteries. It's such a shame 🫠 that CRT was overtaken by the Analog to Digital switchover, back in 2003, or whenever. Then, came flat screen TV's. Talk about JUNK!! Your friend, Jeff!!

I built my Novice Class amateur radio transmitter from a scrapped television chassis purchased from a thrift shop for 50¢ circa 1970.

The transformer was the most valuable part. Got about 350 vdc for the final.

"Excellent video! It would be even better if it had Portuguese voice-overs.

A better title for this video would have been "The death of the cathode ray tube"

Here in the UK we call them line output transformers, or As TV engineers would say LOPTEX.

The clarity though can't be beat on a CRT. I find a CRT monitor easier to read compared to a LED flat panel.

The same thing happened when the vaccum tubes replaced by the semiconductors. When germanium transistors dominate the 1950s to 1960s the silicon boom retired the germanium transistors for good. From 1970s to mid 1980s germanium transistors were on its borrowed time. It should not be difficult to distinguish between two different semiconductor materials however the manufacturing machineries, labors,and investment on R&D towards making better germanium transistors took a sharp turn and forced everything to start from the beginning. It wasn't just the swap, the silicon went far from simple discrete transistors and diodes to the microchips. Not only any vintage technology get ditched overnight the years of skills, experience, hope we built on get squashed for corporate profits.  The OEM also face the repercussions of the market shift and leave them completely vulnerable. Now we have millions of spare parts sitting in shelves for decades just waiting for single chance to work.  Anyone really take these old technology serious may use these over produced long idle spare parts to keep the legacy technology alive.
Now these old tv sets, boomboxes and many more wandering around the after sales second hand market to get one more chance to work, to take care of them, we can't simply let them go.

I can't remember but if you put a very high ohm resistor across the terminals on the tube you can discharge it 1 meg ohm or higher. Yeah those tubes hold a charge for quite a while just like a very large value electrolytic capacitor ( tin can)

If you want to listen to an AI narrator stutter stu stu stutter it's way though a video.. you'll love this.
