A bit late to this thread.? Drake seem to use a lot of the CTS 450 series pots.? I would guess the pot in the AC4 is a CTS 450 series.? You could get one of these from Mouser and swap out the wafer.? ??? Just be careful not to break any of the tabs securing the wafer when you take the pots apart, replace the wafer on the short shaft pot and put it back together.

Thanks David.
Only that the holes are there and I wanted to replace it with what is there as the shaft is very short.

The main thing is finding a suitable replacement and Mouser seems stumped to one.
