Help is appreciated
The Amp is a gibson G20 from '71
original symptoms were low output. (that was last year, now its motor boating)
I have a tektronix audio sig gen but don't know what/how to input signal at the amp's guitar jack input.
Tha amp is "motor boating" whenever I plug anything (sig gen or guitar) If I disconnect the this stage from the amp the signal is amplified and clean when I inject a signal from the sig gen.
Is there a place I can post a schematic of this amp for others to review and help me understand whats what.
Thanks for your time and concideration Steve
