I don't know (I have the B&W head on mine), but I would probably try and see if I could find a fully working one first and foremost, finding parts (trough eBay mostly) can be hard.
- It is maybe possible to canibalize another m670, but then you are stuck with two...(or 1.5 enlargers).
You have something from the official Durst shop though, the transformator for the color head is called "COLITRA 350 230 VN" -I think- (230 stands for 230 voltage, so if you are in the US, this will most likely not work properly)

Still, if you are new to this and want to get started, try and find a fully working enlarger is my advice. (they are pretty cheap nowdays anyway)
