After a long research for a 5x7 enlarger finally I found a Durst Laborator 1300. The enlarger is in very good conditions but I have to disassemble it for transport, but I don't know how to do this and the user manual don't help (I didn't find a manteinance manual for this model).
I think that the enlarger can be divided into 5 main parts: the head, the column, the power supply, the EST1000 and the ECU100 control unit, but how I can disassemble all these parts? For re-assemble the enlarger there is some "special" adjustment that can be done only by Durst engineers? Any help would be apreciated, thank you very much.
