A straightforward linear supply. We should be able to get that puppy working. Looks like you have two of the same thing on G2, two +5V supplies. You could take advantage of that and compare voltages of one against the other at several points. You coukd also monitor the voltage on the non

An easy way to check the caps is to see what the voltage across them is like when you put the system under load and the 'regulated' voltage drops. If the cap voltage drops substantially, or if you get a high ripple under load, that's a good sign the caps are bad. You mention that the +5V holds
