Durst Laborator 1200 calibration; Dursf vs. Beseler 4 x 5

[Mike McMullen]

I am trying to calibrate Ilford Warmtone to this rather imposing instrument - the instructions seem to still be in Italian - ! - can anyone offer any tips? A bit of a learning curve for a guy who has used a Beseler 23C the last 12 years - I'm using the Dursf for 4 X 5. Also, can anyone out there compare using the Durst vs. a 4 x 5 Beseler enlarger with Ilford Universal head? Thanks.

What head do you have on the Durst? What head were you using with the Beseler 23C?
If you have a color head on the Durst, the contrast filtration values listed in the Ilford paper package work well.
