    The fact that it was working before your friend got a hold of it. The caps had to be installed correctly.

    Each diode should have two readings ie. forward and reverse biasing

    Yes. I did opposite readings on everything but the Positive side is not looking good. Should I go ahead and replace this part? It is part #5B2 6C. I read online you cannot find this one any more but 5b4 works just as well.

    No luck finding one on Mouser. Radioshack used to carry a 400V option but all of them are now closed locally.

    Center of one pin to the center of the next pin. 5 mm perhaps.

    The middle two pins are on top and the bottom pos/neg pins are far apart on the bottom. The parts on mouser should work if I bend the pins to fit.

    There is a pic. I’ll try to find a part locally tomorrow first.

    Thanks for your help! I’ll update after I install the new part.
