I have this old Agfa Varioscop 60 enlarger that I paid $8 for, and found it was time to put it to use. It has a Agfa Color-Magnolar f/4.5/105mm lens that needs a little CLA as one of the aperture blades seems a little stuck, but I believe that should be easy to get fixed locally. It seems to take up to 6x9cm film from the variable negative carrier. There`s no bulb above the condensor, what kind of bulb should I buy for it? There is a drawer above the condenser, is it for filters? I`ve searched all over the net for info on this enlarger, but there is very little to find... I pretty much blank on enlarging, as you probably understand I have only done contact prints until now.
