I initially thought that there was a bad relay on the on/off circuit- but after reading the above post - that it actually does not turn off - but drops the volume - there may be an issue w/ the rt channel of the amp - having been driven into ground for so long- it may have a bad cap or tired transistor...
If you do revive it- you might put in a DPDT power switch - just to make sure it goes OFF -
Happy Listening
Follow Ups:
I found the service manual and schematics on line (thank you Google). The output amp is an integrated part - TDA7375AV - under $6 from Mouser. I have a little more experimenting to do before I plug in my soldering iron, to see if I can isolate the source of the crackling noise. But with the manual and schematics/parts list, at least I'll have an idea what I am looking at.
