Tom, I believe you are correct on both points on power generation from the falls.
Here are a few photos of why the transformer is not original to the set. 5Y3 rectifier (wire stubs cut and left). The one phenolyic "standoff" has the same leads just cut and left. One of the electrolyic can caps still has a wire "stub" sticking out from being cut. I also checked the power transformer mounting holes. They appear to be the same dimensions as the original as they were not re-drilled to fit this one. There are a few more bits of evidence of previous repair work. Although, "most" paper capacitors appear original. Also a few resistors appear to have been changed at some point. I spent quite a bit of time cleaning the flyback and area, removing "oily dirty muck" with ammonia on q-tips and following up with naptha. Naptha is also excellent at removing dirt from the flyback itself. It looks like new, however I would NOT recommend using ammonia on the flyback itself, just the surrounding area (insulating phenolyic) and wires. I didn't take any "before" photos. It was completely BLACK with crud.
