Cam, in the case I had it was a brain roller not turning but it would easily be a pad roller or "operator error" which covers lot of things and very often dragging the print soundtrack across the edge of something when loading.

We think it might have been a pad roller, we've lubricated it and now I think we'll run a 9' homemade test loop (from new trailers) through for about 6 minutes, which according to my calculations will be equal to running a print through for 2 weeks (four shows a day).

In the loop we've got a wide range of sound, from heavy bass to heavy treble, hopefully this will work fine!

With prints made on Kodak VISION Color Print Film (that has a conductive antistat on the back side), just be sure the back side of the film runs across a grounded metal roller close to the sound pickup, to provide a path to ground.

I have seen numerous instances of static discharge to the solar cells particularly in cold dry places like Montana and Canada in the winter.

Believe it, it happens. I've even seen it take out Dolby Cat. No. 117 output cards where there is no path that is obvious.

It's best not too be too logical about static and lightning as they tend to do as they please and as I'm fond of saying "the last guy who truly understood all this was Nikola Tesla".

Still, some people like to play with it. There is actually a guy in that suit.
