I was reaching for a box on the top shelf of a closet and my DBX PA+ that was in it fell out and onto the hardwood floor. I dampened the shock slightly with my bare foot (the physical pain was way less than the emotional pain). It still bent the aluminum faceplate some and the rotary-knob shaft has a bend. The faceplate is mostly straight now and the knob still works but the it rubs.
So I took it apart and it seems like a it'll be pretty easy to remove and solder a new one on. The question is should I send it in to Harmon, order the part from Harmon, or check Mouser for a similar pot? I already emailed Harmon and waiting for a response.
It's a spare unit, so not a big deal or priority. I just bothers me knowing it was in perfect condition and now it's sitting in a dark scary closet with battle wounds.

Re: Replacing electronic parts
If you know the value and taper there's no need to involve Harmon.

Re: Replacing electronic parts
If it works, don't do anything to it. As long as it turns and the "push" switching works - leave it alone and use it the way it is.
You could end up screwing it up just for aesthetics.

Re: Replacing electronic parts
That's very likely not a potentiometer in the traditional sense, but rather a rotary encoder. They don't really have a value as such, but can be had cheaply: https://www.amazon.com/s?k=rotary+encod ... ush+button
