Anyone know a part number for the rotary pot/encoder for the M-One XL unit? Mine has gone wonky and will only work if I pull out really hard while turning it. I have a work around where I shaved off about an 1/8th of an inch of pencil eraser and stuffed it between the pot and the PCB...high tech I know, but how long that fix will last is a bit of a mystery. I would like to just replace it but you know TC's stance on that sort of stuff...all very top secret. Anyone got a source on this little beasty?
