Overall, the 1292 is about as reliable as the other 12XX series.. which is one of the most reliable sets out there. I do actually have (I think) a complete set of 1292 tubes here as well, less the colored C elements, which is what I wanted them for when I got them. I do have a test chassis here as well, and most if not all of the boards.

There is a difference between not available at all and available but to expensive.

Ok, I have attached a couple pics below, they show where the XG PJ is currently located (and where a new one will go). Now the XG is NOT permanantly placed where you see it, so dont be shocked Razz

I do plan on mounting a projector directly above the XGs current position, the wall that it is behind is to be completely removed so the floor can be finished and the ceiling and walls finished as well.

The 1st pic is to show the distance between the XG and the screen, the XG is currently at a distance of a little over 11 feet away from the screen, which is 82" Diagonal. 2nd Pic is the PJ Placement.

Will a 1292 work within these space constraints?

Again, dont diss the masking tape! Razz

It depends on how bright you like the image. A HP of that size would probably give you 20 ft/lmbs or more. You can also turn down the cr/br to reduce the wear on the tubes. As for a smaller raster, you will get much better corner focus.

I wouldn't run that set long like that, your throw distance is a mile off.

82" wide screen with a 132" throw? Not good!

The NEC is typically 1.4 X the width of the screen to make good use of the tubes, so you should be at 115", maybe a touch less.

Just FYI.

I can't see from the pics what else you have going on, but why not leave the projector where it is (or even push it further back into the wall), and just make the screen bigger to get the active image area the right size on the tube faces? I know it doesn't give as much seating, but having the projector in a separate room is a dream scenario, because you can greatly reduce the projector noise (which is a huge CRT downside). Heck, put a piece of glass with AR coating on it over that opening, and you could almost completely eliminate the projector noise! Projection booth, baby!

OK, you're good throw-wise. Smile

I've owned two 1292's, one had less than 1000 hours on it, I've owned countless XG's, all varieties, AC and LC.

I'm not a fan of LC, it is softer, period. AC units are sharper. Haloing doesn't bother me, in fact, I don't ever notice it at all.

Currently, I own a G90 and an 808s with MEC high resolution tubes and high bandwidth video chain components, the G90 is my everyday machine, it has new tubes that were installed by Chuchuf.

1292's RATED light output is 700 lumens.

They are dim.

They are sharp, for an LC, but not even close to the sharpness of the G90.

If you are a huge fan of LC, and don't care to lose ultimate sharpness, and you can live with a projector rated almost HALF the output of your present projector, then buy a 1292.

And that doesn't touch the noise factor...they're DOUBLE the noise of your current XG, which is one of the noisiest NEC's, btw.

I hate to be a wet blanket, but thought you might appreciate a perspective from someone not selling anything, who's actually owned all the projectors mentioned and used and set them all up, fairly extensively.

The G90 is very, very bright, and has such extensive focus controls it overcomes the inherent limitations on focus produced by LC. Its the only machine, aside from the last generation Barco's, that have such extensive control of the beam focus. I've never actually owned a Barco 909, but I've had one in the garage and seen it work, and they're close to the G90 for focus capabilities.

The G90, in my opinion, stands alone in many areas, compared to all the other crt projectors I've owned...

Oh yeah, and did I mention its SUPER bright ! Like watching a giant tv ! I don't even bother turning the lights all out most of the time its so bright.

And they're really easy to set up well...unlike all NEC's, haha...and Barco's are a bitch to get stable...

All projectors have good and bad points, the G90 has fewer bad points than most projectors I've owned...and its REALLY bright...

I have to say I think LC is sharper, the light reflected back onto the Tube face from the lens even with AR coating is enough to contaminate the image. The Glycol in the LC chamber cuts that down to almost Zero so its a much more unmolested image off the tube face. You have to remember there is still glycol in AC units and the space is very minimal between the outer glass and tube face glass not giving ample amount of diffraction of the reflected light. With the LC tube there is a much larger gap that allows more light to be refracted.

Also add to the fact that the secondary glass on an AC is flat where the LC chamber has the curved C- Element acting in essence the same way as the flat AC glass. so less direct reflections back onto the tube face and then back out to the screen which are seen as halos and light scatter.

At least thats how I see it, no pun intended Wink

Having said that I really need to swap my PJ's to LC.

As awesome as we all know G90s are, sadly they cannot be had all the time, nor for the price range I am looking at (at least if I buy a G90 thats been gone through by someone qualified such as Curt)

The brightness of the 1292 is really the only concern I would have. I honestly dont know if its sharper than the XG AC or not, never seen one in action. The only Sony 9" I've seen is Jarseneu's G90 when I bought my XG from him. That would probably be a bad example to judge a 1292 off of because its a G90 first off, and second, it looked REALLY REALLY amazing.

Noise, well if it goes in a projection booth area then it wont be a concern for me at all. I'm not in imminent need to purchase a new projector, so if a G90 happens to pop up before I buy a 1292 or something of the like, then of course that would be the one I would go for.

I am merely looking at a 1292 as an option because it is still a 9" CRT which has some benefits over an XG. It would also be my first LC based machine, so I wouldnt mind seeing the difference on a regular basis to see how I like it.

Size and wight of these things is completely irrelivant to me. IMHO CRT PJs are STILL THE ONLY option for a true theater like experience. I have seen countless new digital projectors and of course the zillions of new digital TVs, and EVERY SINGLE ONE of them I can notice lag, streaking, whatever you want to call it, I notice it. CRT is the only display technology that I can watch super fast moving images on screen, and it not only stays sharp, and streak free, it actually looks BETTER.
