I have a 1978 Princeton Reverb for many years. The reverb never worked too well on it - it works, but is not very wet. I checked out the tank recently, cleaned the contacts, but no change. I am pretty much satisfied with my Electro Harmonics Oceans 11 spring reverb setting, but short of taking it to some tech, any advice for a not so hot solderer? Oh, tried different/new tubes as well. I think V2 is often the culprit - no change.
