Tube disposal
#3
Thanks, Kevin!
Now that you mention it, I recall taking my last cathode-ray-tube TV to a special recycling depot, I'll have to look them up again.
As for your comments on tube life, I agree completely! I have a late 70s Ampeg V4-B that I bought about 25 years ago and have never changed the output tubes. It has a set of GE 7027As that a local repair man once told me he suspected were the original set installed at the factory! I have, however, had to replace a couple of preamp tubes that went microphonic or otherwise started making undesireable noises. So, when I say "tubes that have outlived their usefulness" I mean tubes that have ceased to function properly.
