Hi guys
I have this power transistor, it's taken from a Class G Power Amplifier. I already found two short circuit diodes on the Faulty Channel, but I decided to remove the other transistors and test them.
They all test OK but this one is marked B1186A and on my Peak DCA55 it analyzes as a PNP Digital Transistor (which I believe is a transistor with integral base resistor) but if it is a 2SB1186A then it should detect as a regular PNP Transistor.
Having said that I put it in my LCR-4T semiconductor analyzer and that just says it is a PNP Transistor.
So I am a bit uncertain if this actually is a (2S)B1186A and if it is definitely OK or faulty.
Yeah I could desolder the one form the the other (working) channel but the amplifier modules take some effort to strip down and I would rather not have the hassle if I don't have to.
You can see which device it is here - it's the one clipped to the front end of the heat sink you can see me checking it here:
