There are 3 transistors in the 3000-1 that are not also used for FM reception or audio. These are the 121-349 AM RF, the 121-351 AM Mixer and the 121-350 AM Oscillator. They are located in the upper left corner of the chassis (as viewed from the back).

However, it is unlikely that any of these is bad if your Shortwave bands are still working.
