I posted a quick reply, but it seemed to disappear. Today, I attached my signal generator (RCA WR-50B) to the radio. I set the frequency to 900 KC. Brought up the radio and tuned up the middle of the dial, and was able to receive a station very clearly. When I tuned up the band slightly, I could hear the modulation from the SG. When I moved the frequency on the SG I lost the station. I attached my external antenna and could not pick up any stations. Since this is a six tube radio with a 12SK7 before the oscillator (12SA7), could my problem be in the first RF amplifier?
