    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

  3. Meanwhile why not replace all the electrolytic capacitors, (faulty ones can
    cause the motorboating) I would think they are dryed out by now and it would
    be a logical start to the project, maybe even a cure.
