Looking for schematic on Reference 650FET r Receiver

A neighbor had this and said it didn't work, so I thought I'd take a look. It's supposed to be one of the first receivers that had MOSFETs for the output transistors. It's from about 1978 and from looking online it looks to be from Pacific Stereo which went under in the mid 80's. The tuner works and the left side works also. The problem is the right side and there's a little hum in the background. The right side does work, but the bias is running the outputs a little hot. I hope I won't have to try and draw one out, but have decided I do want to take a stab at it. It's a beautiful looking receiver, and on headphones does sound very nice. Googling only brings up a owners manual, not a schematic. I don't need the entire unit, just the amplifier and possibly power supply.

Crossing my fingers...
Thanks in advance,
Steve
