I recently acquired a Super Chromega-C dichroic enlarger. The fan is striking something, causing a vibration of the lens that results in a blurred print. I am able to print with the fan off by plugging the timer directly into the wall socket -- avoiding the power supply/stabilizer -- and thereby being able to enlarge without turning the power supply on. The enlarger is plugged into the power supply which is plugged into the wall socket. Am I losing both the power stabilization function of the power supply and the voltage reduction function?
A second and maybe better question is how big a deal is it to get at the fan to see what is going on and how easy it might be to fix?
Thanks. Dave King
