Have just fell upon a bunch of these panel mount, screwdriver adjust pots that I have no idea what to do with. A41610203 10k 137.6621 is what is imprinted on the side.
Couldn't find a lot of info on these from those numbers. I wish I could find some kind of knob that would fit these but other than 3D printing something I've had no luck. They would work good for a bias control in a tube amp/fuzz circuits. I only have the pots, no hardware. I tried some of the nuts that come with the Alpha pots from Tayda but they are too big. Anyone know how to figure out the nut size? Looking to sell lots of 5 for $10 plus shipping. Bulk discounts available upon request....PM me. USA shipping only.... Sorry guys. Thanks for looking.

I think your right. I found 2 nuts in the box that they came in and they would only tighten down a couple threads then stop. I just thought they were the wrong thread pitch. Thanks for the info.
