I don’t understand all the jargon, and I can’t put a board together. Matter of fact, I can barely solder a wire onto a lug. So when my STTNG 16 opto board started having problems, I sent it out via USPS to a Pinsider who was gracious enough to attempt to repair it. Unfortunately the Postal Service lost it and he never received it. So in comes DumbAss to save the day. He put together a board for me that is better than the original in that the components are raised off the board a bit to help dissipate heat [(I think), remember I told you I don’t know squat about these transistors, resistors, incapacitators...] All I know is the board looks great, professionally done, was cheaper and less riskier than getting a board that only seems to be available outside the US, and the game works 100% again. I would absolutely buy from DumbAss again without hesitation. I just refuse to call him by his Pinside handle in private messages to him though
