Author Topic: Brenkert Question ???? Dick Prather Master Film Handler Posts: 259 From: Portland, OR, USA Registered: Feb 2002 posted 11-13-2013 12:03 AM                     The RCA 100 series was a updated BX-80 built by Brenkert after RCA bought them. 100's had an optional 4" lens barrel. We kept calling them Brenkert 100 projectors. The two RCA machines I rebuilt were called a RCA 200. They were a standard 4" lens barrel Century C with a flat trap & gate. They were painted in Brenkert Brown & cream. They hade the RCA meatball in the glass and a red RCA serial plate in front. Came out of a DI in Sweet Home, OR. One went to the Red Vic Theatre in San Francisco, CA and the other to a collection in Chicago.

As for hard starting..when I had to equip the Crest Theatre in Sacramento 20 years ago, I had 3 days to come up with a two machine booth for 20min changeovers! I had a pair of BX-80s and Motiograph SH-7500s! They did not have the usual leland motors, but had GE split phase motors! They started so fast the pins would break almost every time! Finally found a couple leland double shaft motors, installed a flywheel on the open end, that helped reduce the shear pin losses until I replaced the motios with SH-1012 soundheads years later! The union operator could change out a shear pin in less than 60 seconds!! They bought them by the dozens and had the hanging on a nail in front of each machine!  |  IP: Logged Donald Brown Expert Film Handler Posts: 131 From: Lincoln, DE Registered: Sep 2009 posted 12-05-2013 08:44 PM                     John: Do you know what distinguishes the RCA P 200 that you have from from the RCA 200 B that I have encountered? The operator using it has never been able to locate a manual for that specific model.

I'll bet I can get it for a lot less than $1500... http://www.ebay.com/itm/Brenkert-VINTAGE-CINEMA-Movie-Equipment-35mm-Film-Projector-HUGE-Complete-Extras-/221324453138?pt=US_Movie_Slide_Projectors&hash=item3387f72512  |  IP: Logged John Eickhof Jedi Master Film Handler Posts: 588 From: Wendell, ID USA Registered: Jan 2000 posted 12-09-2013 02:38 PM                        Don, I don't know any differences, however if they were keeping with earlier RCA soundhead specs, the 'B' would indicate 'Brenkert colors' ie: 'RCA Brown' wrinkle exterior and 'Navajo White' interior (MI-9030-B) The 'A' would indicate Black wrinkle exterior and appliance white interior. (MI-9030-A) they were supplied for installations with non Brenkert projector heads. RCA magazines also came in the two different paint schemes. As for a manual, I have one for the RCA 200 but it is simply a Century H/HH parts manual with rubber stamped 'RCA-200' on the cover. Otherwise it matches my H/HH parts manual exactly.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 12-09-2013 04:58 PM                        Every BX-200 I have ever seen looked exactly like a C. You have one that looks like an H. that must be the difference and, the timing is right.  |  IP: Logged Rick Green Film Handler Posts: 12 From: Sacramento, CA, USA Registered: Jan 2000 posted 12-10-2013 06:05 PM                     Hi John, You're right about the shear pins at the Crest. I also got pretty good at changing out the fiber shutter gear in the Brenkerts. The fast start on the Motiographs had a nasty habit of munching the fiber gears!

I replaced a lot of Brenkert main drives (and safety fuses) until I tamed the Ballantyne. 200 watt 4 ohm adjustable resistor did the trick. louis  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 12-14-2013 11:32 AM                     quote: Robert Koch I cant imagine a more nightmarish situation than a Motiograph 7500 reproducer trying to drive a Brenkert. How about a Motiograph 7500 driving a Super Simplex? Talk about going through a lot of G-87's!  |  IP: Logged
