OK, so everyone knew the answer to my question about who lives just inside
Pennsylvania, just past Youngstown.
So, here is question @#2; a bit harder.
KM5M came over last night with a new (old) MM3 keyer as once upon a time
manufactured by AEA under his arm, and it does not key.
One output keying jack shows no activity; the other shows dead short.
I have no schematic to look at, but on blindly opening up the enclosure, I
see two transistors mounted on the PC board that are located close to
those+ and - output keying jacks.
Are these the keying transistors, and if so, what is the nominal type or
value of these transistors ?
I am hoping that this is all that ails the MM3, and maybe I can get it
working for him.
