Hi Folks,
I have a 1970's Realistic STA-2000D stereo receiver. It is pulling over 5 amps at less then 40 volts, with my viriac. I was able to isolate and determine that two of the power transistors out the four on one of the secondary PS boards, are shorted. I don't see any other visual damage on the board. My question is, Will the power transistors go on their own or should I keep going pulling and checking the rest of the components on the board? The transistors that are shorted are B539C and D287C and can be replaced with Mouser #526-NTE284MP.
These are the metal flanged type with two pins.
Thank you,
