Does anybody know where I could find a solid state schematic for a dual
voltage supply that would give about 30v for perhaps 5 seconds then the
full 120v? Or how to make one? I'd like to extend the life of my projector
bulbs. Sure they go out after about 25 hours but I would love to double or
triple that life. For those of you not on the 2 film collector lists bulbs
cost around $23 apiece.

If your not on the film lists then please respond directly to me. The
16mmfilm &fcls users can just reply to the list if they wish.
Thanks very much. I'd like to install something like this in my Kodak Pageant.
