So I'm trying to set up a darkroom for the first time on my own (other exposure has been in great college and school rooms that were already established). I was given a ton of equipment, part of which is a Beseler 23CII XL enlarger. My question is (and this is going to sound really stupid - I just can't remember to save my soul!) - do I have to have a timer, like a Gra-Lab or similar, to turn it on or off? Everything works when I plug it in - the bulb comes on, the lens stops up and down, focus works - all good, except for turning on and off without unplugging!
