Eric, here is quick and dirty troubleshooting procedure. First, holding a capacitor (value not critical .01 or so would be good) in your fingers by one lead, touch the other lead to the center terminal (the wiper) of the volume control. You should hear a hum in the speaker. If so, the audio section is working, at least in some fashion. Next, tune the radio to mid band, say 800kc. Now take a portable radio tuned to 1255 (800 + 455) and place it near your Emerson. Now rock the tuning slightly on either one of the radios. The portable should pick up the local oscillator of the radio under test. By doing these two test, you will prove (or disprove) about 2/3 of the radio circuit.
