Did the other things I said seem to make sense to you? - You have a lot more experience than me..
I don't know how much trouble it's worth to fix up a Bandit.. I guess a little, if you get it cheap, & do it to learn how..
The reverb is really awful on these, & I don't think it's mostly the fault of the tank. Might be fairly easy to fix?
Well,I did some repair work on a Music Man guitar Amplifier for a mate of mine, it was a Hybrid design, that is, it was part Solid-State, and part Tube, anyway, when I first started working on it, it was very noisy, so I went through and desoldered all the original dual op-amp ICs which were old 1458 types, I also replaced all the original IC sockets too because the contacts were very dirty, I replaced all the original ICs with TLO72 types, result....much quieter in operation...
The Peavey Bandit is a well known and respected guitar amp, so I reckon they're worth fixing, you could try totally replacing the original reverb tank with a new or known good second-hand one....
It shouldn't be too hard to mod it to give a better tone, probably no harder than with any other amp, but if the amp is at least over ten years old, then doing things like replacing all the power supply caps, and op-amp ICs, is probably going to go a long way to improving the sound of the amplifier, you could even probably replace the stock speaker with a new one, say maybe a Celestion....
What I would do is search online for a schematic for the amp...
