Default Yamaha M-4 Amplifier

Does anyone have a legible schematic and/or service manual? I'm looking to repair/mod my recent aquisition.

Yes I have a service manual. Is your amp working? They are a real dandy amplifier. I bought one new in 1979 while in the service and it still sounds great!

One channel is blown. I would much appreciate a service manual, but I can't email you as I'm too new a user and under moderation. It is a nice amp, but my M-2 is nicer (also with a blown channel thanks to Klipsch RF-83s).
