Default Denon PMA 770 - Schematic & PCB layout - Anyone got one?

Dear Folks,

My 18 year old Denon PMA-770 is dying slowly but surely. I have already spent $300 AUS with it at the local repair man, and it is still distorting when hot (and it DOES get hotter than it ever used to, I think)

Does anyone have the schematic and PCB layouts for that amp or perhaps its smaller brothers 750 or 730. There was a bigger brother as well, but I am even less sure of its Model Number.

All help accepted with gratitude.
