FDP Forum / Fender Amps: Vintage (before 1985) / 1972 Pro Reverb Intensity control affecting the volume



Measure twice. Cut once
Oct 10th, 2017 10:04 AM   Edit   Profile  

working on a 72 PR that had the dual channel reveb mod and not sure what else done to it. Going to black face the circuit and convert bias balance to bias adjust.
During the preliminary look over I noticed the Intensity control when on 0 is fine. On 10 is totally attenuates the volume for both channels. This was before and after I black faced the circuit. Wiring seems ok for this circuit. Haven't had the chance to replace an caps or resistors in that part of the circuit yet. Any leads would be appreciated. Thank you in advance
