Thanks VERY MUCH in advance!
I am an old school electrical engineer and I have been known to repair audio equipment. By any chance do you have the schematic for this unit? From your description it sounds like a failed transistor causing the noise (a common type failure). Send me a PM if you would like to get together over the phone to discuss further.

I also have tube tester, transistor tester, brand new oscilloscope, signal generator, etc., and I enjoy working on this equipment in my spare time.
