So I found a lot (literally a lot, like 300) of tubes for sale, but they're all from a tv/radio repairman kit. It's like $50, so I might get it and re-sell them anyway. They're all NOS in the boxes, here's part of the ad "Some names are RCA, GE, CBS, Tung Sol, Raytheon, Westinghouse, Sylvania, Standard, Delmonico, Philco, Silvertone, Shield, Motorola, and Zenith.". I was mainly wondering what the odds are that I'll find some that are usable for amp building/replacing tubes, and are there a lot of common sizes used for tv/radio and amps? I'm just getting into tube amps and building amps after 4 years of playing, so it might be a stupid question. And sorry if this is in the wrong place. Thanks in advance

But aren't some tubes for multiple devices but with the same use? Like 12ax7's come to mind, I read that they're super common audio pre-amp tubes, not just for amps

It may have some common tubes, that's a wide variety of brands, odd are that you'll find something usable from 300 tubes. Selling them for a dollar a piece for working tubes still leaves you well ahead, I'd buy them.

Most tubes can be used in audio, rectifiers for different HT voltages, triodes, tetrodes, and pentodes for gain. I'm sure you'll find a use for at least 50-100 of them, minimum.

Ok, that's kind of what I thought, and since he said they're all from the 60's and some from the early 70's, I figured it could be a good deal.
