I'll have to look again. I probably won't do anything until this
weekend. It didn't jump out at me, last time I had the cover off. If I
recall correctly, many things were attached. I've got a Fisher that
needs work (what, I don't know), and the face plate came off that very
easily.

I don't have anything with multiple concentric spindles, on this amp,
fortunately. Looking at the amp, it really isn't the pots that are the
main problem, it's the switches. They are rotary switches, not sliding
switches. I guess that's why I was thinking pots.
