I have a mesa carbine m6 since 2013. A few weeks ago it burned out the transistors and the resistors on the card in front of them. We thought is was caused from a jammed fan. A little plstic pin had been sucked in to it. I had it in for repair at a local specialized electric repair shop. They switched all the burned out components. Last sunday i tried it for the first time after it was repaired. I got through half a song before it turned silent and then it burned again. Have anyone been experiencing this with the m6? All help is gratefully taken.
