The Projection Picture Links of the Williamsburg Theater shows a Marc-300
Kodak 16mm that the description says is inadequate for their throw/screen size.
They should try a Bell & Howell model 567 with its Marc-350 lamp. I have a pair
that I have used at drive-ins and gotten a decent picture. They should try one of
those machines with an F 1.2 lens.

I wish! Actually, I'd really like an Eastman 25 with 1kw xenon and 6000' reel arm
modification, but seeing that the Pageant was put together in my spare time from
junk parts found in a closet, I doubt that it'll happen anytime soon. *grin* A little
more info on our setup: MARC-300 Kodak Pageant (with new-style 25w
solid-state amp), 2" f/1.9 lens (standard) with strange adapter thingie (that's a
technical term) that makes it into a 1.5" lens. Throw distance is almost 80 feet,
image height is about 14 feet, brightness isn't so great. For sound, I just run the
output of the projector amp directly to the center-channel Voice of the Theatre
(Simplex/Altec...basically a bastardized A-7 with Altec 515 15" driver and 299
horn diaphragm) using the cabling that normally connects to the center-channel
amp. Sound quality is OK, but it's still a Pageant (all of them have lousy sound, at
least in my experience). Also makes seamless changeover from 16mm to 35mm
difficult.

Scott:
I have manuals for just about every version of the MARC-300\350 (G.E.) and
COLORARC-300 (GTE/SYLVANIA) ever made. The power supplies are still
being made by a company who took over for General Electric. The company is
NORTH AMERICAN POWER SUPPLIES (NAP). I've got their address
kicking around somewhere here at home. The latest version of the power supply
chassis will directly retro-fit into the case of all previous models and has some
really nice new features like: remote control; dimming (digital and analog); standby
half power; and the best feature of all is auto bulb sensing---- you can use either a
Marc 300 OR a 350---the power supply adjusts itself to the proper settings for
the bulb installed!
This new supply also runs MUCH cooler because it's a switching regulator type
and very stable. Rated for continuous duty.

Hey Ken,
I think NAP is in Ft. Wayne, Indiana.
