    A good friend of mine who recently passed away told me about purchasing his first car, brand new, using money he made from repairing TVs around his neighborhood. He started by running tubes to the local store, testing them, and replacing them. Then, he bought a tube tester and a small stock, which he’d carry in a wagon.

    There was a doctor in his neighborhood with the first model of a color TV, and the tubes would constantly overheat and pop. This was the cash cow that bought him his first car. He eventually realized that he could solve this issue by adding some active cooling to the TV by running a small fan off of one of the TV’s circuits. And that’s how he accidentally killed his first job.

    if dad couldn’t fix it with the tube from the grocery store kiosk.

    I’m both bemused and curious what in the world that might mean.

      My best guess is that they are probably referring to a degaussing hoop. You used to be able to rent / borrow those to try to fix your TV if you kid played with magnets near it. I’d never describe it as a tube though.

        I remember those, but for tape deck heads, not TV’s.

        Anyway, Scirocco came with the very likely correct analysis, if you can see the other comments in this chain.

          Old televisions used vacuum tubes in their circuitry in a similar role to transistors in (more) modern electronics.

          These were literally little glass bulbs with bits inside that heated up, glowed and did magical things with electrons. They had some number of pins on the bottom and plugged into the television board similar to CPU sockets (but with only 5ish pins in a circle)

          These tubes were not particularly long-lived and were fragile physical devices. When they were “on the fritz” it was literally often possible to smack them back into place/alignment/operation. Hence the trope of a TV with a bad picture, slapping it around and voila it works again. This was a literal thing that really happened and works, at least until the internals of whatever tube were too far out of alignment.

          At this point, rather than call an expensive repairman (always a man in those days), you could take your suspected bad tube to the grocery store, where there might be a machine that resembles a 1980s arcade cabinet, which has a bunch of various common vacuum-tube sockets on it. Dad will plug the ‘bad’ tube into the (in)correct socket and the machine will pronounce that tube to be GOOD or BAD with some version of accuracy.

          With that information, dad can select a new identical or similar tube from the rack that’s under the testing board, inside the cabinet.

          Maybe it will work, maybe not.

          Lots of specific tubes were replaceable with more generic versions that “will work” and there was a lot of effort to consolidate the vast number of tube variants, so another important tool was the equivalency chart-- look up your old tube in a book of tiny print/tables and see what generic part number might work to ‘fix’ the TV

          Without having to call the repairman to your house, which was also very much a real thing.

            Ah shoot, I’d completely forgotten about vacuum tubes. Everything fell in to place with that reminder, but it was fun reading what you had to say about these things. Thanks for that nice writeup!

    I’ve always found it interesting how brands that are either not household names or have been mostly forgotten shaped technology that we use every day. You can find LED bulbs or cheap electronics with the Curtis-Mathes brand nowadays but back in the 60’e and 70’s, they set the standard for repairable TV’s, at least in the US. They basically modularized everything to where there were like 10 replacable parts and the repairman carried all of those with him. They could swap out a bad component in minutes.

    Another one that was never a household name is Allen Organ Company. They make electronic pipe organs, which replicate the sounds of an actual pipe organ, sans pipes. In the early 70’s they created the first fully digital organ. It had a small computer that generated the tones. Even though it had a several large PCB’s and a pretty big footprint for its limited capabilities compared to computers today, at the time it was a pretty impressive feat.

    I haven’t owned a tv since 2002. A friend’s kid thew a remote at their’s and cracked the screen. I asked if they could get it repaired and everyone looked at me like I had two heads. “You just get a new one…!”

      Even when Tv repairmen were common, they never repaired broken screens. TV repairmen used to swap out components but not the screen.

      Gone are they days were people get things repaired, especially the “simple things” like getting a good leather shoes sole replaced, or getting a couch redone. Though planned obsolescence plays a role in this as well.

      It also means these services are more expensive as a result.

        Shout out to Bosch… I have a 10-year old dishwasher from them and the drain pump stopped working. It was so easy to replace and readily available. I was actually happy to have it break, all told.

        A lot of enshitification has happened in the last decade so no idea if their products are still like that, but when the time comes to get a new one I’ll certainly be giving them my first look.

        Sad, ain’t it? I repair all kinds of stuff. Have a 50" TV that only needs a new board when I can afford it. The 55" on my wall needed 2 new capacitors, $8 on eBay.

        when I lived in the UK there were shoe repairmen everywhere, they were great, and if the repair was easy they wouldn’t even charge me.

        in the States I haven’t seen a single one

            And even then it seems like the boots theory is dead for most stuff. Even when you buy the “premium” products they fall apart and are made of crap materials or are designed to be irreparable

            For me it was more about how much longer they would last. The soles they gave me were better than the originals. The rest is just small stiches and patchwork I can do at home

        There’s a shoe repair shop in my town. People absolutely do get simple things repaired what you can’t get repaired are things like TVs anymore.

        But things don’t break like they used to, it used to be that a component would fail and you could just replace that broken component but everything’s integrated these days so if one thing goes down the whole thing is dead.

      You may not own a tv but do you own a computer monitor? No one fixes those either and a tv is essentially a monitor with an extra control board. The screen is the device.

      Replacing the LED panel of a common 65in flat-screen TV costs almost the same amount as a brand new TV and months of time, and money to ship between the repair center and your home due to the weight; lol of course they looked at you like that, you sounded silly, innocently ignorant and ridiculous.

      It was weird to see an actual vacuum repairperson on Breaking Bad. I understand that that wasn’t their primary function, but it seems like in the modern world the front wouldn’t stand up or at least would be subject to extensive scrutiny.

      That or the price of advancement has made things impossible to fix without swapping out entire components or just get a new one. Which has been taken advantage of by making things fail a lot sooner. So much easier to make it cheaper so it gets replaced, and it keeps the company in business and is more profitable.
