Carver PCX850 service manual/schematic

Hi there.
Can anyone assist with a service manual and / or schematic for a Carver PCX 850 Stereo Power amplifier?
Or if you know a link to download this from - would also be a great help

You can also e-mail me at "workshop at industrocleanpe dot co dot za."

I know this is not really HiFi but I'm desperate to repair this old amp.
