Author Topic: Motiograph SH-7500 Questions - Jaxlights and Wiring Cody Martin Expert Film Handler Posts: 214 From: Edinburgh, IN, USA Registered: Jun 2004 posted 05-17-2006 09:45 PM                        Hello Everyone, Hope someone out here can help me. Though I know jaxlights are not a great solution by anymeans, I have came across a couple sets at the "right" price. I was wondering if anyone has a picture of one of these in an SH-7500. It seems like the clearnance is pretty tight...can anyone confirm this? To get it to line up with the buld I had to adjust the bayonet base on the bottom of the jaxlight..no big deal, but again is this something others have had to do? Lastly, I was wondering if someone can show me how the routed the solar cell wires in the soundhead. I'm afraid of them getting caught in the film. Thanks for everything, Cody  |  IP: Logged Tim Reed Better Projection Pays Posts: 5246 From: Northampton, PA Registered: Sep 1999 posted 05-18-2006 07:00 AM                       Does the "right price" involve someone paying you to take them? I wouldn't wish Jaxlights on my worst enemy.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 05-18-2006 11:35 AM                        Why not use an LED conversion? Kelmar (at least) makes one for the Motio. The cable goes back toward the gear side of the frame, above the thumbwheel, toward the lamphouse, terminating just under the old exciter location. The wire does not penetrate the wall where the thumbwheel is.

I acquired the jaxlight kits(2.5, one bad exciter) with a purchase of some guidance parts. As this is only for my personal use I believe the jaxlights will do fine...for now(eventually I will go with a led conversion). Still looking for the a picture of this if anyone has a similar setup.

The top of the Jokes Light heat sink HAS TO BE MACHINED SHORTER in order for it to fit under the slope of the top of the main casting....... A certain Film-Techer put these mesly critters in all over Montana and Idaho and I'm in the process of slowly weeding them out.... Last week I got to run over a couple of them with the van so they would never be put back into service again . The theatres owner applauded!

If you do install the Jaxlight, be careful about taking flash pictures of your booth while it's running. It could lead to catastrophic failure of your speakers... or your audience's eardrums!  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 05-22-2006 07:29 AM                     quote: Jack Ondracek If you get the $$ to do it, the CE conversion that Greg mentioned works very well, and doesn't require that you modify the soundhead to get it mounted... other than to take out the exciter lamp bracket... and that's just a matter of 2 or 3 screws. Tyhe Kelmar also fits right in place as well. I've installed quite a few reverse scanners into SH-7500's and unfortunately these things just don't pop right in as Jack says. Its actually a pain in the ass sort of job to accomplish and getting the exciter mount back in place is the real treat during the job Mark  |  IP: Logged Jack Ondracek Film God Posts: 2348 From: Port Orchard, WA, USA Registered: Oct 2002 posted 05-22-2006 11:03 PM                        Guess I don't quite follow you, Mark. The exciter bracket is a big brass arrangement in that soundhead. How do you put it back into the same space the pickup now occupies?... or am I just reading your comment wrong? You are right about it being a pain to remove though. The screw in the back of the soundhead requires that it be removed from the base to get to it... unless there's some cool tool that can get back there.  |  IP: Logged
