Thought I would start a new thread for this since the topic is different.

While building my power supply everything was going fine until I guess I shorted something out on my low voltage side and didn't know it. I ended up applying 20V to the C11 and now when apply 5V I get 4 LEDS that light but and one of the chips near the parallel port just heats up. Anyone thing getting a replacement set of Buffers and optoisolators world get the board running again?
