I have a superstar 121 cb radio and it will not key up. The TX light is not come on. No output. Found a transistor missing. TR32 is what is labeled on the board. Would this cause my problem? Any help will be appreciated.

Hi AndyA I would look at the simple stuff first...... the mic.... Open the mic make sure there are no broken wires , if you find one solder it back where it goes..... next look at the mic plug at the radio end.....same deal open inspect and repair if needed. Start there and see if that fixes the problem..... if not post back and we will dive a little deeper. I'm not familiar with that radio at all so some pic's might help....good luck
