Thanks for all the help!
I'm keeping the Rollei. Not sure about the fan situation, but the enlarger seems to be in working order. The Nikor 50mm is in great condition, metal version.
I won't have a dark room for a while, but currently learning B&W film development.
What is the red filter on the enlarger for?
You can position a sheet of B&W paper under the enlarger without exposing it that way. Personally, I only do this with small test strips, to be sure I get them where I want them. With full prints, I position my easel using regular light from the enlarger and a dummy sheet of paper (the back of an old print that didn't come out right).

It has a regular 3-prong plug, i.e., not a special plug to a transformer. On the back it says "Input 120 VAC, 50-60 Hz, Output 82 VDC 85 watts" (for the Omega Cat. No. 471-400 Quartz Haolgen lamp). Does this mean the voltage is reduced and converted to DC by the enlarger as-is? Looking inside the head, I would have to take a good part of it apart to see if there is a diode circuit that does this (there's not much room for a transformer and the head doesn't feel heavy enought to contain one).
You can most likely see two transformers in this Craigslist listing for two Nikor colour enlargers: http://vancouver.en.craigslist.ca/va...926323229.html

I have an Omega C760 w color head. It has a separate voltage stabilizer (which is a small unit) that has 110vac input 85vdc output. The stabilizer plugs into the timer and the head plugs into the voltage stabilizer. So it sounds like your Rollei has the stabilizer built into the head.
ooops, did not realize the thread was so old
