Realistic STA 2100D Guidance Needed

[JerStC]

I have a 2100d that needs a replacement treble pot, I can find one for both an STA 2000, and 2200. Are either of these a compatible replacement for a 2100d?

It looks like the shaft may have been broken and the prior owner rigged it to work, but it moves in a non circular motion and one has to press it in to get the treble to change. I'd like to replace it.

Any help would be appreciated.

I wish there was a cross-reference for parts for Realistic equipment.

I suggest to get the service manual for the2100, 2000 and 2200 and go on a fishing expedition to see if the controls are the same.
