Thanks guys ... I appreciate your input. By way of explanation, I'm returning to B&W photography (35mm and 6x7 MF) after a "lifetime" of working. I'm in the process of setting up my darkroom, and being a retired Engineer, I'm a bit anal about reading instructions. The instructions I got with the enlarger relate to the Magnifax 4 .... hence the question.

Ian, thanks for the link - I've downloaded the data sheet and will work my way through it.

Steve, there probably isn't an issue - I'm just used to dealing with complication !

Stoo, I'll send my email details to you and thanks for the offer.

Again, thanks to all.

David
