Actually, that was my first thought and I did exactly as you have described. That had no effect. I didn't really know how much signal to expect at Q13 and Q14 but with the previous reports Q13 seemed more likely. That turned out to be the case

The big kids usually handle these but this time I am going to take a stab at it. This sounds like the final PA is not receiving the supplied DC power. Or the PA is blown, and needs replacing. Without the PA working at all, you can still hear a signal on
a "nearby" receiver being produced by the driver transistor loud enough to hear. At least this was my experience.?
Clip the leads on the PA instead of desoldering, and solder you new thinned and shortened PA leads to the backs of the original leads still on the board. Because you are going to do this more than once. ?Let's see if the experts agree.
