What's the lead spacing for the active leads? It should be 10, 22.5, or 25 mm.
Edit: It looks like 22.5 mm from the photos, but it might be 25 mm. I calculate 23-23.5, assuming that the dotted circle underneath the PCB is 35 mm. Oh! Some Nichicons come with 22.0 mm spacing. So it could well be 22 mm.
2. i still have to figure out how to trace the waffle plate with the diodes and fets,
Yeah. That might not be easy to replace. If a couple of devices shorts out, it might be necessary to replace them with discrete components on longer leads, bolted separately to the heatsink. Ick.
Then again, the hard epoxy might be the type that melts at a specific temperature, and you might find that those are standard components under there. But I suspect that they might be bare semiconductor dies.
but it appears that these caps hold up the first DC buss created by a diode bridge across the AC input and before the PFC circuits.
Right. So like the 2-3 capacitors in the PFC stage of the Elcon chargers, not like the one near the MOSFETs. Hopefully, they have proper snubber capacitors, perhaps on the Waffle Place™. (I love that name
