[Frameworks] Xenon Arc Conversion for Super 8
Hi all, Does anyone perform, or know of someone who performs, a xenon arc conversion on Super 8 projectors? Specifically, I have an Elmo ST-1800 I would like this doing to, so I can show Super 8 reels in big spaces. I would be really grateful for any help!

Re: [Frameworks] Xenon Arc Conversion for Super 8
Is that projector rated for such conversion? There may be spec issues that may not allow it. As far as I know only certain brands / models could be converted This subject was discussed here some time ago...

Re: [Frameworks] Xenon Arc Conversion for Super 8
A guy called David Hanson in Belgium came over with a converted ST-1200 for the Aurora festival a few years back. He used a Gemini Xenon and added a PC cooling fan.

Re: [Frameworks] Xenon Arc Conversion for Super 8
Not to confuse the matter by introducing infor=mation that goes nowhere but... Brodsky Treadway (BT), in another century, published a guide for conversion of the Elmo GS-1200 to xenon projection using what was called a MARC-300 Power Supply. Their instructions included info on how to do this, how to drill extra holes for mounting screws and everything. The joint I work for—San Francisco Cinematheque—had one of these units that worked great until someone stole the power supply (but not the projector) from someone's car and that was the end of that. At one point (long ago) I wrote to BT about their conversion guide and was told that the info was out of date. I didn't (and still don't) know what that means. Sorry this isn't more helpful...
