    Hey, I am in need of some help figuring out what's wrong with my amp. It's a '94 or '95 Fender Twin Amp. The reverb and effects loop stopped working on all the channels but the distortion channel, even then it's more like the effects are "in the background." Any help and advice would be greatly appreciated.

    Do you have an extra preamp tube you could swap into the reverb send slot (IIRC, it's V4 or V5)? If not, pull V1 and try it in that position. Tubes are always the first suspects...

    I've already replaced all the tubes, they needed replacing anyway. but I took a look at the wires going to and from the reverb tank and inspected the tank itself, but I don't see anything obviously out of the ordinary. Is there anything else I should look at or try?
