It has been awhile since I have looked at Stewart's perf screens. I didn't really like them that much, but I am not a fan of AT screens except the Seymour Enlightor 4k. IIRC I did look at the Stewart screen at Cedia and the rep said you could not see the perfs. So, I did a quick test. I walked back and forth to see what distance I could see the perfs, which I think was around 8 to 10 feet or so. The rep then replied that you couldn't see them at regular seating distances.

I believe Seymour's XD screen was around the same. Personally, I would like a margin of error if I were going the AT route.

I know you are looking at Seymour's XD material. Cliffy's room is real dark and the weave isn't that noticeable. Of course, I don't believe I ever did a comparison with a regular screen in his theater. It would have been an interesting comparison. Maybe the next CRT showdown. Wink

15 feet is probably fine, but don't quote me. Your best bet is to get a sample. I have some somewhere, but I have no idea where it is.

These 2 are the worst of the lot, it's not this bad in person due to flash however, the wear doesn't make sense, there is no wear pattern, nothing, the whole tube has same colouration, what gives?

Either they ran max tube face for very long hours at low outputs or the glycol is stained. The blue on the second pic looks to have stained glycol, since its clearer in the center.

How many hours on the sets?

The OZ Theatre material have a 1.3 gain.

My initial thoughts were stained glycol as well but these were maintained by Barco Technicians whom I know.
The sets have 22 k hours on them, yikes! Very Happy

Perhaps the tubes don't have many hours. The stained glycol could simply be from some sort of contamination in the LC tank particularly if the tubes were replaced using the original tanks rather than switching out the entire unit with the LC tanks. I would have said exposure to reflected sunlight but how would you get that in planetarium?

If it was sunlight id expect it to be rather uneven, and probably have buggered C elements.

I know they were well maintained, i spoke in some length with Phil about them on the phone, but they were indeed sitting unused for a long time!!

you SUCK, and yes, the glycol is bad. When getting projectors from planetariums, they're projecting black all the time, so there's little tube wear. Watch for pinpoint phosphor burn from stars and planets though.

In January I'm getting in 9 Barco 1209s from a planetarium as well. Some have new tubes, others will have slight wear. Will get my 909s running, and will sell stuff CHEAP! Smile

got nothing new to report other than the Onkyo receiver is back from extended warranty repair. Nice, for only having spent $30 on a remote for it. Very Happy

I am crazy busy with sound quotes and installations, and may have a big job to be done by the end of December. If so, no holidays for me, and no time to work on the stack until Jan..
