Concentric shaft dual pots? Can they still be found? There used to be kits to make up various combinations as needed.

Thank you both for the thoughts.

Regarding the fitting of a 2 Meg pot in place of the 12A6 grid
resistor, I'm reluctant to do that, because it's too much of a
modification in a set that is pretty original. Also, there's nowhere
to fit another pot.

I think I'll fit a 620 ohm pot on the LM-380 board for (preset) level
adjustment and hide that board in the receiver's outboard power
supply, then use just the RF/IF gain control that is already in the
set for audio level adjustment.

I think my question's been answered.
