Please view these photos of a three-turn planetary drive pot that uses a conventional "stackpot" formfactor at
It was made in 1966 by CTS; stampings: 36129 137.6637
Does anyone recognize this pot technology? Any suppliers nowadays? I need the form factor for modifications to antenna rotator assemblies in a space that does not permit using larger multi-turn pots and using trimmer versions is not sufficiently robust.
