Jim, there are a couple of problems with this approach. If this amp has 
indeed been modified so irresponsibly, the wire colors could well have 
changed. What if, for example,  you were to see an orange wire in the 
picture hooked up to C56 +, but the orange wire was now doing something 
else? And, no matter how beautifully photographed, I don't think I would be 
at all comfortable with following what I think I see in such a photo. The 
only way to wire this amp right, in my humble opinion, is with a complete 
understanding of what you see on the schematic.

The first, and easiest part, is that a terminal trip long enough to hold 
the three or four largest electrolytics can have the ground side bridged 
across the lugs with grounding wire.
