Ok, so I was rebuilding a power supply that came out of my tron. It I finished except for the two big resistors on the heat sink. After hooking it back up I would get a loud hum in the attract mode. Once you coin up it's fine. I tried adjusting the voltages, but now I can't seem to get the pots to work and the +5 is stuck at around around 6.3 and the +12 at around 13.4..I've tried moving each pot to the max in each direction w no change. Any idea what I screwed up here?
EDIT: I noticed when I accidently touched one of the transistor legs at Q012 with the multi meter lead the hum would go away, but when I took the pressure off it, the sound would come back again. I tried replacing it with the original, but the sound was still there.
