Hey guys and gals, I just picked up a Peavey Special 130 on the cheap because the reverb was not working. I thought I knew why because the pan was missing! However, I put in a known good Peavey part number correct reverb pan in, and no 'verb. Disconnected the OUTPUT RCA cable from the pan, touched the tip and got noise. To me that would indicate that the issue it's on the input side. The amp has the Burr Brown mod, no cracking pots, and all solder connections seem solid. Y'all got any idea where I could start? Does the foot switch (which I do not have) circuit automatically shut off the reverb without a footswitch? I can't tell by looking at the schematic (attached). Thanks in advance for your advice/input!
