This has been on my list for a long time - well, it's now at the top so lets give it a go.
The issue was the right channel was not working, so more of a mono than a stereo. I managed to download the service manual from 1998 which included the circuit diagram but it looked so complicated!
I've got a scope, multimeter and misplaced confidence so how hard can it be?
