Doing some more digging, I was able to find a model number on the board that says "MCL-427F". Googling that results in a
cap replacement kit for arcade monitors. That's interesting, but not much else to find, and the board in question doesn't look similar to mine.
However, I found an
eBay listing of a CTP4100 service manual which also has a P79 chassis, and the power board looks quite similar to mine. Luckily the seller has taken an image of the schematics, so I might be able to use this as a reference. I will do some cross-checking tomorrow.
