Fully functioning Traynor YVM-6 PA Amplifier hand made in Canada in the early 70s. I’ve tested all channels and replaced the original spring reverb tank with the best new equivalent I can find. Solid state amp ready for a new life. Original reverb tank also included.
I suspect a ground issue in the reverb circuit as there is some hum as the gain increases. I’m not sure how the effects loop per channel was supposed to work, but I’ve been able to blend in external effects from a pedal board on each channel. Where there was scratching I removed knobs and cleaned the pots.
