Wwe have a mitsubishi M-A4370 Stereo Power Amplifier. The unit plays intermittently and shuts down. The power amps STK-4044V is OK. Transistor 2SD1985 (TR901)gets hot and the unit shuts down intermittently. I replaced the 2SD-1985 and I still have the same problem. If I spray cool the transister the unit will start up and shut down again. I have no service if. Anyone have any info as to what may be causing my problem.
