Default Circuit diagram for a Sugden Optima 80

I have foolishly offered to fix a Sugden Optima 80, and a circuit would be extremely useful. I currently have an output offset voltage on one channel that won't null out, though not huge. The power supplies are balanced, as are the +/- 18 volt regulators. I'd rather not trace out the circuit.

Thanks in advance

John

HI all! I also happen to own a Sugden Optima 80 integrated amp but do not have the schematics. Can anyone spare a copy? Thank you!
