[sdiy] nord modular control knob

[Rude 66]

guys (and girls!)

can anyone tell me anything about the big round controller knob on the nord
modular? (the one you go through the patches with).. i have one here where
the knob is all loose, and doesn't make contact anymore. on opening it up,
it looks like the knob was pushed down too hard and the circuit board
underneath bent. when i push it back, it still doesn't make good contact
with the small metal bits on thew actual pot. it's supposed to 'click' but
it doesn't.
would this be fixable? or does it need to be replaced? where would i find
these?

thanks and have an excellent solder-drenched 2003 you all!
