what would I notice if I swapped one of my 9500lc ultras for a G-90.

Also I have extra 9500LC Ultra tubes. Could they be used in a G-90?

Are you talking about specifically for use in a stack? Or just generally?

Generally. Potentially in a stack, but would be interested in the following comparisons:

2 9500LC Ultras stack - to 1 G-90
2 9500LC Ultras stack - to 2 G-90's stack
1 9500LC Ultra to 1 G-90

My two cents:

G90 Pros and Cons:
+ Better beam control (all controls electronically, including CPC magnets)
+ Smaller spot size (uses LUGs by default)
+ Better stock lenses (HD10F)
+ Better geometry allows for side-by-side stacking
- More noise (can be modded)
- Green color is not accurate. Change C-element.
- More difficult to repair/find spares/mod
- No mods readily available

9500 Ultra Pros and Cons:
+ Better video chain (especially 03P). This can be modded even further.
+ Very easy to repair/find spares
+ Mods readily available (Tim, MP, etc.)
+ Can be upgraded with better parts (HD10F lenses, LUGs, frankenyokes, etc.)
- Worse geometry controls. I believe side-by-side stacking with Ultras is NOT feasible
- Worse beam control (I think the default focus yokes are the worst of all 9" machines, and start blooming at contrast 60ish).
- Worse stock optics for stacking/blending applications (GT17/HD10 vs. HD10F)
- Worse stock tubes for stacking (you'd want a smaller spot size for stacking)
- Red color is not accurate. Change C-element.

I have never seen a very conclusive answer on the inability of the Marquees of side-by-side stacking, but the Marquee manuals always refer to top-bottom stacking and this image (from the Reference Imaging website) is very telling:



IMHO, the G90 is a machine you'd want not to open or tweak, and cross your finders it doesn't break; whereas the Marquee is a tweaker's dream

The post above is a fair comparison of the 2 projectors.

As for the tubes, you can use the marquee tubes in the G90 with a small neck board mod, however, if your Marquee tubes are already mounted in the LC housing, it's more trouble than it's worth. You would be better off selling the Marquee tubes as is and buying new tubes for the G90...the price is the same for bare tubes.

I have heard that a G90 puts out more light then a 9500LC Ultra, but checking the specs on Curts website it looks like they are the same?

Also can you turn up the contrast more on a G90 because of the tigher focus and the better lens?

finally if you need to replace the CRTs, how much are a set of new ones?

thx,
Jim
