Trying to diagnose a loss of Reverb AND tremolo on an AC15cc1. Not sure if they stopped working at the same time or not. Not very familiar with this circuit...
Schematics:

The rails on IC1, IC2, and IC3 all check out OK, 3 volts off. (27v, -27v, 27v, -27v, 15v, -15v)
Checked the footswitch with a dummy plug. Touching either reverb + produces no buzz, reverb shows up maybe 5% when the tank is tapped. So quiet I can't tell if it's mechanical or electronic noise I'm hearing. Checked with a different tank. Any direction would be appreciate! Thanks!
