Rod,

Sorry, was relying on my prior explanation and photos and trying to avoid saying "short" wire.

There are at present two wires in question disconnected and taped in the photo: the short wire between tone control and where Capacitors 56 and 57 tie together; the long (originally blue, dangling in and outside the chassis at the right in the photo above) wire which on the schematic runs between tone control and the first solder point on the terminal strip (with Capacitor 47 and Resistor 46).  Nothing has been connected to the tone control pot since I began working on the radio as far as I can tell.

There are two previously-soldered lugs on the tone control pot but no indication that I can see as to which might correspond to which wire.

In the previous configuration, the short wire mentioned above may have not even been connected at all, and the blue wire was soldered to a ground point on the chassis near the power transformer.  I think it was your thought that someone had permanently grounded the tone control for some reason.

Best wishes,
Roy
