    Were you aware that it doesn't work when you bought it?

    So I cracked this bad last open and probed around a bit with the old multi meter and a schematic for the old 3210 board. After allot of probing I couldn’t find anything wrong. So I plugged it in. Red light came on. Rectifier is rectifying. So obviously next step would be plug the thing in, hook it to a guitar and play it. And you know what? Works... 2 pots are pretty stiff and one is bent a little. But it seems to work fine. Got a lead 100 for $50 and it works.

    E8EDF868-3E8F-4346-8143-CC3EFB32777F.jpeg It does seem that there’s an issue with the reverb tank tho. Anyone know where to get a replacement?

    Congrats on the amp purchase. Hey, that’s probably a US made Accutronics 3-spring reverb tank. They don’t make them like that anymore. Company was moved to Asia but there used to be some former workers in the Midwest who would repair the original tanks. Not sure if still around. Worth getting fixed if you can find someone who can do it.
