I was given this enlarger. It has all the condensors. It also has a color head called a Pavelle 401. The Pavelle attaches in some custom way that I havent figured out yet, but all the parts are there. I would use it for black and white VC only. And then there is the possibility of using a cold light. I heard that a particular Aristo fits into the slots where the condensors fit. Does anybody have any experience with this Pavelle head, or using the cold light with this enlarger?
