I know this is a long shot but does anyone have experience repairing these? I combed over every inch of the board for hours and I see no noticeable burnt components. Voltage on the top of the two regs measures a little over 25.5 volts. I think it's supposed to be 30v (+15 and -15) but a video I saw on youtube makes me think it's within tolerance. I'm only getting like a half volt measuring between the legs of the two big pink resistors. It's my understanding the board sticking up in the bottom right corner is what takes +-15 and gives 5v between the big resistors? Any ideas? Thanks.

Yes 5V
You are correct that you should be getting ~+5V across the 2x 150ohm 2W big pink resistors. The board in the lower right hand corner of your image controls this so I don't think your board is functioning. The good news is that if you are getting 25~28 volts across the vRegs then your power supply is working. This pdf should help with test points.
