Dan, My colleague Josh Miele has a busted one also and I've thought about doing just that. Not sure I can fit it in the case because I don't have circuit board fabricatin techniques available
Wouldn't need the new encoder, have to see if the one they have may still work If you have one that is physically O.K. and don't care if you ever see it again, send it along and i'll see what I can figger out. No cost, of course, that's what we're here for. and no promises about success or time either. but would be fun to try. tom
