Unload the outputs. Fire it up. See if you have sorta proper voltages on
the outputs now. If so, replace small electrolytic capacitors in that
"back end" that has you confused until it will supply a voltage under
load. If not, replace the +5 and perhaps the +12 output ripple filter
capacitors (your post tells me you can understand this).
If there are any blown fuses, forget I said anything and consult a tech
near you. (a REAL one, not the guy at the computer store)
