Some friends gave me a nice used Beseler MXII enlarger which has one issue I can seem to rectify. The top and bottom plates that hold the film holder do not clamp down tightly and have a slim horizontal light leak around the room. Is there some way to adjust the height a fraction of an inch so they close tighter. I am using the round Beseler 4x5 film holder and its pins fits nicely in the circular opening.
2nd issue: I put a new 250W bulb into the 45Dicro head and zero'd the color filter values. The recommendation by Ilford is 41Yellow and 32Magenta for grade 2 on Classic MG Fiber paper.
I have run some contact prints and found that too contrasty compared to a filter under the lens. I cut magenta down to 16 and got closer. Is this common due to new bulb, or possibly the mixing chamber? Any adjustments recommended or merely alter print by print?
