Reply to "MTH PS1 Bottom Board Keeps Blowing"

Ok if these are original harness you are good. Now that I see that 9V solder job that could have damaged that regulator which also allows voltage to go high tracking with track voltage. That causes the buzz can cause a loss of the resistor and can damage the top board.

If the top board got damaged that may have caused issues with the new bottom. Or you damaged the regulator when swapping boards.

I have board I can sell. You can send me the 2 bad board sets and I can test and make sure they are working fine.

When moving boards that insulator needs to be in place and you need to ensure the regulator does not get damaged in the movement. G
