These were a DIY project a couple/few decades ago. Now you can buy a motorized Alps pot with the controller board, IR receiver, and remote for $30-40, and just retrofit it into your vintage preamp that lacks remote volume control.Why is there not a clamp on (on chassis and knob), battery powered little motor with remote offered anywhere? Wouldn't look nice, but having remote controlled volume is nicer.
In the oldern days you could buy two sprockets or pulleys that attach to a 1/4 inch potentiometer shaft like a knob from Small Parts Inc, along with the requisite drive belt or polymer chain…
