The older schematic says it's 33uf at 25v so the 50v rating is ok and 33 to 100 uf i'm sure would be ok their ....maybe some rf got into it an let the smoke out ...good luck

A 70 amp supply should be fine even if it is a Pyramid. I would add a fan to the heat sink area of the amp and don't over drive it.
