Mike, nice to post a link to the schematic for help. Many early radios used the "volume" control to attenuate the antenna and work some wonders on the rf gain. Basically, the audio section ran wide open with the level controlled through the front end of the radio. It sounds like your pot is fine. You need to do some recaping and resistor checking.

Here is a link to what I think is some information on the radio including a lot of wiring etc. Perhaps this will help you and others in your problem. It looks to me as though there are two pots on the same shaft, one for controlling the gain in the RF and one for the antenna.
