I got one of those helipots. 20K resistance. It was a real pain in the ass to get one with all 4 gangs the same value though. Actually mine is 5 gangs but the first four are 20K. And I couldn't find a single modern "servo style mount" for it. Though I might just be searching wrong. I know I had a devil of a time finding good toroidal transformer mounting kits, but once I found a part number, it turned out Mouser carried them all along.

 

EDIT: Wink, you know the resistance in the 4 gang one you listed? I never bought that one because it's not in the description and I wasn't able to backtrack the part code earlier this year. I just never wanted to gamble on it, if it was 1K or 200K or something.

those are wire wound and are linear pots, not log. designed for chart recorders and other antiques.

collins thing was 48 steps solid silver contacts and precision resistors. designed for radio station mixing boards, and millions of rotations.

Mtoc why are you buying headphones and attenuators when you don't have a working computer? please stay safe
