Change pots - Have you done it?

I found a RME that looked very good but the panel light knob is wobbly so I was thinking, maybe I could do it myself? I haggled it down to 1000 gbp from 1300 gbp, it looks good, panel is bright, the serial is RM1115 so It´s not that old and it´s out of the faulty danger zone ranging from serials 1330 thru1925. I figure the pot is 50 gbp including shipping or so?

Would you buy it and fix it or move on?

No one has changed any pots yourself? How about had them replaced by Moog techs?

I don’t own an RME, but changing a pot is no problem if that’s all it is. They don’t cost 50£. Is it the knob or the actual pot that wobbles?

Consider these:
How often will you adjust the backlighting? Is it worth opening it up for that?

Why is the pot wobbly? As a studio unit this points to it being dropped at some point.

It’s the pot itself that wobbles. Yeah I asked the seller the same thing, how can something so sturdy get that banged up? It’s built for taking a serious beating. But he just said that someone must’ve turned the knob too hard lol. Supposedly it has been sitting in a studio for a few years and not getting much use. Anyway I haggled it down £300 and I figured I could fix it myself.

Yeah it probably won’t matter but I’d like it to be a friend for life, or if I decide to sell it I’d like it to be in good shape.

Remove the knob. Tighten the nut. Put the knob back on.
I have to do this every few years to the pots on my Signature. Use 'em a lot and they will get loose.
Use a nut driver or socket and NOT pliers or wrenches and you wont scratch anything. (I have sockets with soft faces that won’t scratch. Overkill, but left over from an OEM I worked for.)
