Info / schematic request

I have aquired a Claricon 27901 four channel receiver. No date code found yet. This is a really nice unit. Only thing is that one of the rear channels (I think rear right) doesn't work in 4-channel mode and when you put it in stereo only (2-channel) it only has one channel sometimes and it might be fuzzy or weak. So right now it is on 4-channel mode with just the fronts working perfectly.

I am inclined to believe that the problem is either in the preamp section or in the selector switch on the back panel that chooses between stereo and 4-channel. With no input and a speaker connected to the outputs, each one has hiss in all modes. So, any help is appreciated.

Thanks in advance,
