Title: Volume pot part number for a tower model?
Post by: DejahThoris on August 02, 2019, 07:23:00 AM
Does anyone happen to have the part number for the volume pot on tower models?

Previous owner mangled the pins on mine.

I think it's basically a Dual 10k Ohm Alps potentiometer similarly to this one

https://tech.alpsalpine.com/prod/e/html/potentiometer/rotarypotentiometers/rk09k/rk09k12a0a2k.html

but with a smaller stem, probably specially made for sharp or no longer produced.

I have replaced the one in my Expert by modifying the stem.

The stem on that part (https://www.mouser.com/ProductDetail/688-RK09K12A0A2K) is way too big to really modify. How did you cut it down?

I thought about just cutting the assembly open and just swapping the shaft over but the old shaft is what actually broke.

It might be possible to 3d model and print a new knob that will fit, but that would be something of an ordeal.

Turns out that you can cut it down through careful and measured flushcutter abuse:

Installed it and it works great. You may want to order more than one pot in case you mess up - in my case I had to file the connecting end of the knob down very slightly.
