I have just repaired two of these rather nice amplifiers.
There is no schematic or information available, so it was experience alone!
The first one was fairly easy; Distortion when increasing the output level. I replaced the MOS FET output stages and that sorted that one.
The second had weird noises and distortion; replace the Sony BX chips and repair the power supply fault that caused the problem in the first place.
I replace the power supply components in the first one as well as the second for added reliability.
I do like a challenge.
