Well, like carbon arc, I didn't care too much for motor-generators. They were a lot of work, too. I think people who worked on them are fondly remembering a time when a projectionist was a real craftsman, and maybe forgetting a bit, the maintance required. If you ever had to have the armatures removed and worked on, you know what an unbelievable mess happens in your booth. I particularly hated filing new brushes to match the curve of the commutator. Messy job.They use to use little motor-generators for two-way radios (in cars and boats) in the 30's 40's and 50's. It was to generate the high voltage for vacumn tubes from the car's 12v or 6v battery/ generator (the high voltage was called the "B" battery.) Motorola used to call their motor-generators, "Dynamometers" if I remember. They made a nice one that fit in a 4" x 4" x 12" box.

>>"Dynamometers" if I remember.<<Close. The little motor-generators (what 'MG' in 'MG-Set' stands for by the way) used in military and mobile equipment were called dynamotors.
What about the old exciter supplies in some of these places that used a pair of Tungar® argon-gas rectifier tubes... Boy I miss the changeover days...

I may be slow but I can take a hint!  ...I went to the Carolina Theatre today. I just got my digital camera today so I was dying to try it out. Here is what I found out.  She's still there and looking pretty good for her age. (Built in 1927) -- Please ignore the lens flare!  It's owned an operated by the United Arts Council of Greensboro. They run a full schedule of events there: Stage shows, concerts and last but not least, movies.  It is on the National Register of Historic Places and they are also a member of the League of Historic American Theatres.  Here is the schedule of films for the 2000-2001 season. I missed The Man Who Shot Liberty Valance by one day. (Damn!) You can also check out their site: http://www.carolinatheatre.com I only got to talk to the girl in the box office today but I got the guy's name who's the operations manager. I'll try to call him up and get in to take a few shots from the inside.
