i just obtained a very clean (albeit modified)specimen of a Traynor YGM-3 "guitar mate" combo. the design allegedly resembles a fender deluxe reverb(PP, reverb, tremolo).
problem is, the amp is not functioning correctly, it has a "spitty" distorted sound at any level. i haven't checked voltages yet; i opened it up and noticed an "auricap" on the plate of the 1st 12ax7(anode>capacitor>volume pot) which seems like the polarity might be reversed. the schem doesn't indicate polarity. attached is a photo of the suspect cap. anyone know if this is right? i'm sorry for the dummy question.
next step is to desolder and reverse and see what happens i guess.....
