Hello, parts gurus.
I recently acquired a Focusrite iTrack Solo that has an issue with the Monitor knob. The headphone and line outputs only work when light pressure is applied to the knob. Let go and a second or two later the Left channel cuts out, then the Right. This occurs over the entire range of the knob, and there is no scratchiness that might lead me to believe the problem would be solved with contact cleaner.
A number of other owners of the Scarlett Solo 1st Gen, 2i2, 2i4, et al have seen this issue and some have temporarily resolved it by applying pressure to recrimp the metal tabs and enclosure around the pot. This resolved the issue for about 5 minutes in my case and then it was back to the way it was.
It has a panel mount Delta brand pot with marking A103. The shaft is D-shaped / flatted and appears to be 6mm wide x ~10mm long. There are 6 small pins in a row at the bottom and two larger outer pins connected to the pot's metal enclosure and tabs.
I think I'm looking for an A10K stereo pot, but how will I specify the pinout and size? A quick look on Digikey didn't turn up any small-quantity options so I suspect I'm not looking the right way.

Have You tried Mouser.com ? Look in the alps section.
You could disassemble the pot and bend the wiper contacts.

Thank you for the suggestions.
The closest thing I could find on Mouser was the Alps RK14K12A0A3C, but it has 7 pins rather than 6.
I reached out to Focusrite to see what they say.
If there are no other options, I will try to pull the pot to see if I might be able to re-bend the static wiper back into place as described in this guide.

Looks like the Alps RK12L series could do:
https://www.mouser.com/ProductDetai...%2BO9hPGG/W9Ptmxa2ti8UDziCZLnYQbE3jgM4o6xPA==
This appears to have all of the necessary specs: 12mm snap-in with 6 pins in a row, horizontal mount, 2 gang, flatted shaft, 10K, audio taper, no detent.
The only downside is the 30mm shaft length. Maybe I could hack it down.
