Greetings:

Please view these photos of a three-turn planetary drive
pot that uses a conventional "stackpot" formfactor at
http://www.cybertheque.org/homebrew/...tennas/pot.jpg
Resistance = 1K

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.

Regards,

Michael
