Could a Marquee GT-17 lense be used as an Anamorphic lense in front of a digital machine? Or would it just be a throw distance increase/decrease situation.

Hello,
no a LC lens like gt17 can not be used. You can make tests wit AC CRT lenes (Hd6 hd145/144, Hd8...). If you find the right distance to the digital panel, or better if you can get close enough - it might work. But as the digital panel is much smaller, you will have a increased throw (not if compared to special long throw digital lenses). And I am not sure if the edge focus of CRT lenses will work with a small digital panel.
Keep me updated!
Marc
....and there is nothing anamorphic about a GT17!

Dave I have a buyer for those lenses. CXturbo is looking for a set.

Thanks but I'm not selling anything yet. Remember I bought an 8500 Ultra not to long ago and I have a spare set of 9" tubes and housings too. I'm getting a digital doing 2.35 scope and most likely rebuild the 8500 too. This way I have a way to confirm which is better.
Not really, they're different a will do things better in one way and not the other . So I will have a choice as to which one stays or gets used the most.
I pretty sure the GT-17 wouldn't work Anamorphic, but asking saves a lot of time setting up the experiment.

How could they work Anamorphic with digital, if they don't do it with crt?
Lens should recognize is light from digital or analog projector and then if it's from digital, chance only vertical refraction angle smaller.
