I hooked up my NAC PSU today to check the voltages...
I'm getting good 120v, however my 12v was jumping between 10-10.8v, my +5v was jumping between 4-4.8v with the adjustment screw turned all the way up...and my -5v was just reading 0...unless I was using my meter wrong when i was checking for that...
Here's some pics, it's a 400-5198-01Y:

Any input on how to fix this up? Here's the numbers off the 3 chips that are attached to the heat sinks:
K2236 5K...I think this is a voltage regulator?
61 D15SCA4M...has diode symbols on it, I think it's a rectifier?
58 D5LC20U...also has diode symbols on it...
Cap list:
50v 0.47uf
25v 47uf
50v 10uf
200v 330uf
10v 6800uf
10v 6800uf
16v 2200uf
50v 10uf
25v 100uf
Do any of you guys have any advice on what you think I should replace to get these voltages back to where they are supposed to be??
