Marantz SR-4000 amp board

Hi. I'm working on a Marantz SR-4000. I see a couple other folks here have worked on these units. I'm new to vintage electronics and unfortunately someone did some previous work on the main amp/power supply board and it appears they removed some caps and diodes from the top and bodged some others onto the bottom of the board. I think they may have been trying to bypass some circuitry from blown STKs. What I'm looking for is photos of the BOTTOM of the amp/power supply board in factory condition so I can see what I have to undo and what is supposed to be there. I don't see any of it on the schematic to indicate these mods but I'm not great with schematics yet.

Thanks!
