I have recently set up a black and white darkroom in my basement. After buying a gralab 450 timer off ebay I made my first prints today. I noticed though that every so often after i pressed "start" the enlarger light would take up to .5 seconds to come on. Also, after being in focus mode, it sometimes won't switch over to time mode. Is this a problem with the enlarger or the timer? Any ways to fix this? If it helps, the enlarger is a Beseler 23II with a color dichro head. Thanks in advance.
