Check ebay for a seller called chipforbrains or something similar and
 he sells at least volume (oscillator, main) pots and the push buttons.
 I believe the push buttons for the polysix work for the push buttons
 for the mono/poly. Someone told me that 808 buttons work too, but I'm
 not sure about that.
 Also, I'm fairly sure that all of the mono/poly pots are 10k with
 volume being logarithmic and others (frequency) being linear.
 Good luck with your search.
