Default Re: McMichael 381 Valve Radio project

Looking at the last photo posted it looks like the volume control (R15) might have been replaced with a standard pot (no tap) hence nowhere for the disconnected wire to connect to, I would have thought that if it was connected to the "ground" end of the pot (the one you've highlighted as a possible connection) then the Foreign setting would have an effect if the rest of the negative feedback components and connections are ok.

The disconnected wire shouldn't affect the reception when using the press buttons.
