In looking at the schematics that are posted here
http://www.nostalgiaair.org/PagesByModel...013585.pdf
the volume control looks to be incorporated in the same control with the power switch. Looks like there is some radio/phono switch contacts which enable and disable some of the radio circuitry so you may want to take a look at giving those a shot of cleaner such as DeOxit and switching them back and forth a few times and then seeing if that helps.
Another thing with these old sets that usually needs to be addressed are replacing the paper and electrolytic capacitors. Are you getting a loud hum with little phono audio, or just low audio in general?
