I'm trying to get my Pengo up and running and I have determined there is a problem with the original G-80 power supply. Measuring +5 and +12 without the game board connected I get +5.1 and +11.98. All good. Hooking up the PCB drops the +5 to +1.9 and the +12 stays about the same. The PS board looks pristine with no charring or really anything bad looking.
Which parts should I be testing? All diodes and fuses test fine. The TIP141 looks like it provides the +5 -- is that correct? Any other parts that could cause the drop in voltage?
