NEED of a REPLACEMENT CROSSFADER for UMIXcontrolPRO2

Hello support,
I have U-Mix Control Pro 2 with what looks like a hardware problem on the crossfader.
I would like to replace it.
Where and how can I find a new one, same or compatible ?
Or at least the specificiations that could help me find a compatible one.
Thanks a lot.
