So... I have an MTX BTA 2100 here. The problem it's now having is it is blowing the MPSA06 in the remote turn-on circuit. Collector is B+, emitter is to Vcc of the 494 thru a 10R resistor and the thermal switch, base is controlled by opto that is switched via remote wire input. If you short C to E the amp will power up and idle fine. I can't find any problems other than this transistor failing. I see this transistor also powers the 494 output collectors thru 75R resistors. Can I install a TO202 device like an MPSU06 to handle the start-up current draw or is there an issue that I need to take care of? I have another one of these amplifiers and it did not need any change to this circuit.
