Is there any documentation on how to test the voltages on these? There are 3 pots that I assume will allow for adjustment of the different voltages but I'm not sure which controls what nor do I know where the test points are.

I believe Gorf, Super Pac and Mappy also use the same PS.

Thanks!
 
looking at the schematics, you can grab +5V from the + side of C102, ground at the - side, adjustable at VR101. you can grab +12V from the + side of C114, ground at the - side, adjustable at VR102. this was educational, I asked the arcade to buy me multiple cap kits for Midway power supplies.

also the Midway Medium Power Supply was used in Super Pac-Man and Mappy, but not Gorf. I don't know the numbers for that one off hand.
 
Huge thanks! Any idea what VR100 adjusts?
oh I forgot that. -5V I would guess. that has a tantalum cap. I'm not home now but I think you measure that at C101 + side.
