Hello. I have a 1964 Fender Reverb Unit that was completely original when I got it. It sounded fantastic but made the occasional noise here and there so I figured it was best to recap it. I only replaced the filter caps and the three electrolytics on the board. It sounds great--just as good as it did and without the extra noises. But now, when I turn the reverb unit off it doesn’t bypass the signal to the amp like it did before. The oddest part though—it actually does pass a signal, almost full strength, for about 45 seconds after I turn the switch off. Then the volume quickly fades to zero and no signal gets to the amp. I’m reluctant to use it for any length of time worried that I might be damaging something. Any ideas for what I should be looking for when troubleshooting this issue? Thanks for any advice.
