Hey guys.
I received this little amp for free from someone who told me they switched it on and saw smoke coming out of it. I have always wanted to try my hand at fixing old amplifiers and thought this would be a good place to start..
Fast forward to today. I have so far replaced one shorted output transistor and the other three which were also bad, I also replaced two of the smaller transistors (one was completely split in two) and one 4.7ohms resistor which was burnt.
Now the only other fault I could find were these two RGC22 emitter resistors which seems to be shorted? I get a reading of 0.000 when testing them on a dmm in diode mode.
Apparantly they don't make these RGC22 dual transistors anymore, can I just replace them with two normal transistors instead?
Here's a pic of the culprit (the big white one with 3 pins):
Anything else I should check for?
Thanks
