Hi, I have a durst multigraph enlarger (blue tinted chassis 3000) and a durst L1200 (gray chassis) with a condensor head. I tried to put a 80mm lens onto the gray L1200. But i found out that the bellow at it's highest point is still not enough to get it in focus. When I compair the chassis with the newer multigraph chassis, the bellow can be much more compressed. But the maximum bellow extension of the multigraph is less than the older model. When enlarging onto 24x30, the multigraph will need a tube. Is there a way to adjust the bellow? The bar which moves the bellow up and down, could this one be adjusted in some way? I hope someone got the same issue and knows a solution so I can use both systems for 4x5 and 6x6.
