I have a Fender Passport 250 that let the smoke out of a couple of the
transistors on the power amp board and went into protect mode.
I replaced the failed transistors (very carefully) and it worked!!
BUT, once I really put the screws to it for a minute or two, (singing etc)
it smoked 'em again. (seems fine if left idle or spoken short bursts through the microphone.)
Where do I start? What have I missed?
Any help is GREATLY appreciated. This P.A. is used in a church and for my daughters newly formed band.
