Hi Cliff

The bump sound on your rotor sounds mechanical. The wood rotor could just be
loose on the mounts. As far as the pot change, it is straight forward.
Mouser.com sells circuit board pots with long shafts. Or you could use
standard ones mounted thru the current holes. We have done both over the
years. The balance of the rotors is pure to your taste. Good luck!!
