To be honest, it looks more electronically complex than I would have imagined considering its age (from around 1976).
I pulled out one one of the (two) main energy storage capacitors today. It measures 2.75" diameter by 6.5" tall. The ratings are 43.4 uF, 2 kV EACH! This translates to a combined rating of 173.6 Joules max. Charging to 80% would be 138.88 Joules - SHOCKING!!!.
I have not yet figured out if they are used in parellel or series or alternated as they connect to a (3) terminal inductor type looking thing and a black box that measures 1.5 x 2.5 x 3.5". Plus the inductor? It looks like it has (2) coils in it, one has fewer turns that the other. Maybe it's a feedback/transformer/inductor combo, I really don't know at this point. Before I can power it up, I have to try to trace out the interlock circuit and it's related jack & pin outs. As you can (maybe in the pics) all the wires are harnessed, but have NO FEAR, Mr. tie wrap cutter is here.
Plus for the power input requirements, no where is there any indication as to if it's 110 or 220, single or (3) phase. the (female) power jack's has (4) pins, and 4 wires. It could be 220 VAC (maybe three-phase), or 480 VAC. or (HOPEFULLY) 110 VAC with a common and ground wire. :)
Now for the pics:

There is a large standard looking transformer, under the center circuit board, this extends almost from the front panel to the heatsink in front of the fan. This power supply's circuit design is very different from the other one, above.
