Author Topic: Static on RCA 1040 Soundhead? Sam D. Chavez Film God Posts: 2153 From: Martinez, CA USA Registered: Aug 2003 posted 11-05-2008 10:39 AM                       I believe I am right and the static is travelling from the film through the drum and somehow through the chassis of the Jaxlight or the line amp. Static is very strange and the last guy who truly understood it was Tesla. Is the line amp chassis attached to the projector?  |  IP: Logged Al Biers Film Handler Posts: 13 From: Speedway, Indiana USA Registered: Oct 2003 posted 11-05-2008 10:57 AM                     Better idea, dump the JAX and purchase one of Sam's BACP, problem solved, they work.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 11-06-2008 06:04 PM                        I really can't think of anything neutral or good to say about a Jax-light.

It is approx 4-5 feet away from the projector to keep it away from potential hum issues. Pardon my ignorance, but what is a BACP?  |  IP: Logged Sam D.

These are made by Kelmar, Component Engineering and BACP, which is my company. As it happens BACP does not make a reader for RCA 1040, only a 9030/9050. All reverse scan reader are superior to a Jaxlight as they include all new electronics and imaging lens. They cost a bit more than a Jaxlight, but you get what you pay for.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 11-08-2008 06:26 AM                        Sam, would have thought they were the same??? 9030/1040 Louis  |  IP: Logged Tony Bandiera Jr Film God Posts: 3067 From: Moreland Idaho Registered: Apr 2004 posted 11-08-2008 12:48 PM                     quote: Louis Bornwasser I really can't think of anything neutral or good to say about a Jax-light. Louis Then your experiences with them are opposite of mine. I had installed a few dozen of them in various locations, and until recently had one in my own projector, in the course of several years of use had only one pre-amp module go bad, and U*S replaced it no questions asked. Remember what it was designed as, which is a low-cost alternative to the (then) much more expensive reverse-scan readers. In that respect, with a decent slit-lens assembly it performed well. Now of course, reverse-scan readers have come down in cost and gone up in performance. And the BACP is by far the best in terms of quality, reliability and value. Oh, and Sam, why won't the BACP fit in the RCA 1040?  |  IP: Logged Sam D.

The 1040 exciter cabinet is shorter than the 9030 and the back of the reader hits the metal louvers plus a little. I've actually had one person saw out the back of the cast iron sound head to make it fit, but I would send business to a competitor rather than do this kind of butcher work. This is not the world's best sound head, flutter and wow wise, so I never made a version for this one or for the Motiograph although this is the first system I ran.  |  IP: Logged Tony Bandiera Jr Film God Posts: 3067 From: Moreland Idaho Registered: Apr 2004 posted 11-08-2008 11:57 PM                     Thanks Sam, that makes sense. I haven't had any hands-on with a 1040 for too many years, and forgot about the housing size issue. I was of the mindset that the slit lens barrel was the same size...thus should not be a problem. I too would refuse such a hack solution.....too bad the previous owner of my XL head didn't feel the same way, they hacked it to allow pic and track, and now I can't mount a door.  |  IP: Logged
