Hi again,
The Philicorda is up and running again (even brought the old spring reverb back to live) - next on the bench is a Farfisa Compact Fast. One oscillator is not working, I found a supsicious part again, but couldn't find any info on that - Looks like a transistor but which model? Any substitutes to recommend?
The part says: "5gs 1w 9810/3 1738"
I've an old and probably rare (fully transistorised) Philicorda Organ on my bench with no sound output. I've traced the fault down to the amplifier section where I suspect the following part:
Is that a voltage regulator? one of them says: "127/1 2 S H" the marked and probably broken one: "132/1 3 N B" (although the lettering isn't the best). The 132 model has roughly 18V on two legs and ~32 on the third connection, whereas the suspicous one outputs 600mV.
Sorry for the maybe stupid question, but I'm still learning - hope you guys can help me out once again
thanks in advance
