Guys and Gals, I just replaced 4 toshiba mosfets in a technical pro 2 way loudspeaker, active type. I thought it was the end stage output so the company sent me the mosfets (100 watt each) anyway, one nite it just blew, it went high on everything including bypassing volume controls etc, a huge static noise then i turned it off and used my back up, a gemini 900w....... i opened it even with the waranty because these boards come from a manufacturer in japan who is basically out of business because of the devastation over there, technical pro honered the warranty on anything else except the board and sent the parts. im a novice audio man, electrician by trade but digital is mostly what im familiar with. anyway i re installed the mosfets, double checked they were in, check all ground connections, checked basically everything from any shorts etc, turned on the power, gave it a signal (some music) and nothing....... its got the green power indicator/led so the fuse is good, the power supply looks perfect, i didnt check it but i could but it looks pristine, can anyone give me an idea what else to check? the crossover looks pristine as well. Jim
