Hey, that's a good idea! 
But what's good on a Wurlitzer Piano cannot be bad on electronic
components. Heard about cutting parts off ceramic capicitors,
but not filing resistors, so far.

Question is do we risk any other damage from the vibration that is
involved. Or, taking it one step further, would it also work with the
resistors already soldered in? (vocoder "file-tuning", opamp and ota
offsets ...) I guess the solder connections would be stressed too much,
and a file needs space to work ... so maybe fixing the resistor with
epoxy on board, and using a little rotary grinder ?
