Philco 41-90 Questions
#1

I have a Philco 41-90 farm radio which I was given as a gift. I needed to completely rewire it and replace most of the components. I now have it working electronically. But I need to restring it. Does anyone have information on how to do that? I have the string but no idea how get needs to be threaded.
One other question. Does anyone know what the receiver sensitivity should be? Right now I can get an audio tone with an RF signal of -80dBm (22.4uV) @650kHz.
