I will post a pic of the other side. Gunrunner hooked me up with Digi-Key for the triacs. They are part number IRFZ48NSTRLPBF, they cost 1.55 each. I don't think it can be a very big problem but if I knew what I was doing I could fix it. I sent MTH an email asking if I could purchase a new board but I have not heard back from them. I checked the triacs with a meter and on one side when I turn the know the voltage goes up and down but on the opposite side nothing happens.
