      No schematic yet...Hoping to find one when I open'er up. Can't do any lifting. Just got a kidney stone blasted...peeing cherry Kool-Aid and fragments of it. Other options were worse. It could be a slow repair. eh?

        Ugh, hope you get better soon
        Lacking schematic and doubting any will appear soon, start by you providing some info, he he.

        1) describe motorboating: how / when / does it respond to any controls?

        2) usually supply or decoupling related so provide closeups of power supply, specially main and auxiliary filtering capacitors.

        3) fire up your scope,show what appears at output, scope all power rails.
