M4000 schematic Diagram / board photos??

[Bluerunner]

Anyone have a schematic and or photos of a M4000 class AB amp circuit board? A photo of both sides of the board would be nice.

The circuit board around the keying transistor circuit by the relay is corroded away too badly to determine what the original connections were to resore it.

Looks like the previous ownmer might have made a repair with acid core solder and then stored it in a damp place. When I cleaned away all the green hair that was growing in that corner of the circuit board the copper traces went away too.

I can manually activate the keying relay and the amp works just fine at 400 watts. Too nice not to fix it up.
