Jupiter 6 potentiometer shaft diameter

Hey everyone,

Looking to source new knobs for my Jupiter 6 and was wondering if anyone knew the shaft diameter of the regular pots and the smaller ones on the bender panel? Thank you.

All of the Jupiter 6 rotary pots have 1/4-inch knurled shafts. They use a T-18 knob, which is a standard configuration which means there are 18 teeth on the shaft.
