The Harry W. Davies molding company of Chicago makes control knobs. The
Buchla 200 series used the 1600 and 1200 series knobs. The Serge uses the
1900 series knob. The combination of the Xicom pots and the 1900 knobs is
nice, and it is easy to work with for most people.

I expect if you have very large fingers you would need a larger knob and pot
spacing to be comfortable.

The Radioshack part number for the 1900-H is 900-2553 at $0.80 ea. They fit
perfectly on the 0.53 shaft Xicom pots.
