I'm going to meter the illumination output between condenser and color head tonight. If similar, maybe it's just the lower wattage of the bulb. I'm not printing color so I don't need stabilized power, just the correct voltage to the lamp. PDH provided another 100w bulb so I'm back to the local lamp shop to see if they have a lamp converter which would work.
I printed before daybreak with a member provided 601M condenser set and glass inserts. I'm very appreciative of the assistance from Apug members. Used the recommended 75w bulb, 645 neg, enlargement factor 5x (6x8 in centered on 8x10 in). Ilford PQ developer, 20c, EMAKS G3, exposure 30s at f8, 80mm clean Schneider optic. The same neg would have printed less than than 20s on a LPL or Beseler B23c. Is this typical and why Durst mentions a 150w bulb.
