I used to build little amps for all my punk friends using salvage from old TVs. I believe I've elevated recycling to a high art but that's just my opnion.
You can actually build
two amps with junk from an old tube TV. Operative term:
Old. The best parts come from '50s TV sets. By the mid- '60s the build quality on some sets had gone to hell.
The power supply and 5U4G rectifier tube work for a medium powered amp. It's a matter of tracking down a pair of audio output tubes and an output transformer. 6BG6G tubes salvaged from, you guessed it...
old TVs can be used as 6L6 / 5881 subs.
You just need to find a couple 12AX7s. If your set had a phonograph in the console they'll be in there.
Just about every old black and white set uses a 6AQ5 (or equivalent) for an audio output. The difficulty is if you use the oversized power supply from your typical set you'll launch your poor little 6AQ5 into space.
Any cheezy little tube power supply is more suited for a single audio output than a B&W TV supply.
You will find 6CG7s that are useful in late '60s Ampegs in some sets. At one point Magnavox owned Ampeg. The jokes was Ampeg used "TV tubes", not your usual 5U4G / 6L6 / 12AX7 lineup.
Early sets use quite a few 6SN7s.
Some sets use familair tubes with weird filament voltages. I was rummaging through my junkpile tryin' to find some 6CG7s. You guessed it... they're going to New Jersey. That's where Ampegs come from! I could probably sort out a bushel of 6CG7s but today is
International Weird Filament Day (and I didn't get the memo.
) Anyone need
8CG7s?! Who thought 8 volt filaments were a good idea?
