Question Yamaha MX-630 Power Amplifier schematic wanted

Hello everyone,

Normally I am troubleshooting my selfbuild equipment, but an uneducated friend of mine fried one channel of the Yamaha MX-630 Power amplifier by shorting the speakerwires.
Now all the Sankens have to be replaced including the drivers.
What puzzles me is that some small resistors (not in the powerchain) are also overheated. Maybe they were underrated by designmisstake, I am not shure. I also would like to replace them because I think it is a fire hazard and a great liabillity factor.
You help your friend out but created a fire bomb and destroyed his house (including the amplifier) in the end.
I have tried to contact Yamaha directly in order to get a schematic or service manual but I have been not succesfull as of yet.
Can somebody help me to retrieve at least a schematic of this amplifier ?
I would be very greatfull.
Thanks for reading.

Bij voorbaat dank.

Govert-Jan
