Schemaitc for McIntosh MAC-1900

A friend of mine (who is compterless) is trying to fix his McIntosh MAC-1900 receiver, and I wondered if any of my fellow Audiogoners had a schematic from a service manual that could be scanned and emailed or copied and snail mailed. Of course, I would pay for an incurred expenses.

Thanks in advance for your help.
