yeah i think its the switch itself too - as even in HP everything else appears to function normally.
this is the best pics of the 3 position sliding switch on the microbrute board. it appears to fit the same slide switch parts on the minibrute board schematic. i cant find the switch arturia use here (with the alum tube-arm) on ebay, ts-electronics, or any component supply sites ive visited, they all have the black plasic arms ... anyone have any ideas where i could find this particular switch?
