    if you can't focus your lens is most probably to short for the bellow. You will need either SEIPLA, LATUB or DITUB2 recessed lens mounts, depending on the focal length and whether your had is a 138 or a 138S (there is no 139 head - a 139 has got a 184 Stand and 138 (S) Head). You will need condensors 200/130 for 80mm and 130/85 for 50mm focal length.

    The answer about the recessed lens tube likely nails your problem. The shortest lens that enlarger can focus on a flat board is about 100mm. Another source for durst parts like this is photo-graphic systems in Albuquerque, New Mexico. Call or e-mail and explain your problem, they'll steer you in the right direction.

    On the condensers---using the "wrong" condensers should not result in gross focus problems. Problems related to the condensers would be either be obvious light falloff at the edges (if the condensers don't cover the negative, and you are fine in that regard), or very subtle differences that you might not even consider problems.

    Get a lens tube and see if that makes you happy before spending anything on condensers or cold lights.
