Krell KSA-200S schematic

My Krell KSA-200S won't switch on anymore. It does not have a real mains switch, therefore always some circuitry is connected to the mains. This is most probably exactly the same board as used for KSA-100S and KSA-300S, so such a schematic is welcome too.
I think the board was damaged during a thunderstorm, since then it does not switch on anymore.
Reverse drawing the schematic would be one option, but a cumbersome one. Therefore I first try here.

Thanks in advance.
