Drat! Wired up the pushbutton assembly and still no audio. I've done some testing and the audio section is ok. But I can't get a modulated 455kHz signal through the AM section. Then again, I'm not certain I'm actually injecting a modulated signal. I have a B&K E200D that's just been sitting for 30+ years. I did open it up and clean all the switches and controls, and I know the carrier is there, but don't know if it's the right frequency and don't know if I'm successfully modulating it. I guess I need to test my test equipment before I test the radio!
A side question. Is there a good (safe) way to clean the speaker cone? This bad boy is in GREAT shape, but is quite dirty.
