I'm pretty liberal minded, but as a guy, I'd NEVER post the above sentence on a public forum.

Yep, it pretty much kicked some serious ass. And you can't beat the price he got it for. Like 400.00 delivered |
Ray, you scare me sometimes. It was $600. and I had to drive my pickup with a blown head gasket to go get it before he sold it to someone else. I had to move fast on that one, I knew it wouldn't last very long. I was prepared to pay twice that amount, and even that would have been a smokin' deal.
Now quit telling the guys about my room.

If I was a G90 owner with good tubes and wanted to stick with CRT, then I might get a trashed tube Marquee for back up. The Ampros and Barcos probably aren't to bad. Scott could answer the question of if there are any unavailable parts for the Ampro. There should be enough used parts floating around for the next couple of years to take care of the Barcos. For Marquees, Scott has mentioned that VDC will be supplying parts into the middle of the next decade. That should be sufficient for the last five CRT users still around. |
Actually I would say the Barcos 1209s models are also very safe choice. Sure they are no longer in production but you can raid the common 1208 chasis for most parts other than tubes/lenses. Also I have yet to hear of a Barco 1209s with a glycol leak which is more than you can say for the Marquees. They are rarer and newer on average than the Marquee 9500s so maybe that is why we hear less about gycol leaks. I don't know but the 1209s also seems a very safe choice for me. But then I have two so parts are mostly not an issue for me.

You're taking the worst part of 2 different projectors... the outside edges... where focus drops off and uniformity decreases 15%. Then you're taking these worst case edges and making them the dead center of a huge image.
Then you're fighting against color shift if you have any gain at all on your screen material... the left projector is shifting in one direction, the right projector is shifting in the opposite direction.
It's not a question of IF you'll see the blend, it's a question of WHEN you'll see the blend. And it's usually during large solid fields (sky, fields, snow, etc) and when something pans throught the blend zone and during fades to black.
And yes, the split throw distance means your projectors are closer to the screen. So instead of having one projector slightly behind your seat, you're now staring at the ass end of 2 projectors between you and the screen with 10 RGBHV wires running everywhere. Plus, since the throw distance is effectively reduced, your keystone geometry is more extreme, so you also have to take that into effect (and double it)when you're trying to align the blendzone.
Oh, yeah. You also have to throw a blending proce$$or into the middle of all of this. As if HDMI/HDCP wasn't enough of a PITA with a straight shot between the source and the projector.
It's just a personal preference and one man's opinion, but I like stacks 10x more than blends. |
Thanks for the reply. I see why that would be annoying. Even if you could get it looking nice, it would be tough to maintain.
Could you use a HTPC with dual monitor support for the blending processor?
Ok, now the stack question... That's when there are 2 projectors shooting at the same screen yes? Wouldn't that also be a PITA too? Now you'd have 6 tubes to converge on one spot.
I just don't know. Interesting ways of doing things though. 2 decent 8" lc units cost more than a single 9" lc unit from Curt though. I still think I'd prefer to get a 9"lc unit. Come on lottery!

To answer an earlier question re: LUG tubes and 1292 focus coils...
The lugs are the high resolution 9" tubes used in the Barco 1209S and 909.
They are similar to the LQF used in the g90. The focus coils from a 1292
sony are a well regarded upgrade for the Marquee - there are several threads
on various forums about this.
On the subject of blending - the blend processors can cost as much or more
than a PJ. Keeping two projectors perfectly aligned is a personal choice,
much like those who believe heaven on earth requires more than one wife.
As far as using two 8" PJ's for a blend - I hear a lot of talk about it, but never
have read of someone actually putting together a finished system. After the
first blend meet at William's a couple years ago, I borrowed a blend processor
and set up two custom BG808S LC machines blended on a very small screen
down in my shop - just for fun and education.....On a 92" wide screen this
was a very bright system (~22ftL) - but (there's always a but....) the BG808S
does not have the fully capable geometry controls of a Marquee, nor does
it have the Marquee contrast modulation system (Barco does have a very rare
CM board - but it is not very well implemented for blending - yes, I had one)
All this to say - the idea of two relatively inexpensive 8" machines doing a pro
quality blend has been tested, and in my opinion the myth is busted....
You would need two nice & new tubed Marquee Ultra's to really make it right,
and you would still have color filtering issues and would still have the inferior
8" optical system with the AC halo problem causing reduced contrast.
Blending is truly awesome for a 12' wide 2.35 "cinemascope" screen - I could watch
it all day and night...but when you are watching 16x9 all the advantages are lost.
I will be happy just to get my room done and have just one PJ running that I can
'set and forget' - with as little tweaking as possible, the fun of that has worn off....

Ray only got an 8" from me.... or was that a 7"... seems like the jury is still out on that one. It's a 7" that they call an 8".
The list says it's an Entry Level model... Rankings? Who needs rankings?

Well I'm not worried about AmPro support and parts. I have 3 complete X600's and enough parts to build 5 more

I happened across the thread about a discontinued chip for G90's that is really important and would like to know more. Is this something that could easily happen to the other 9" sets or were there that many more 9" sets made of other brands that parts aren't an issue, or unlike the G90, do other machines not have a "one-off" chip (or other part) that isn't used in another machine making parts scarce?
A large portion of people call the G90 the pinnacle of CRT, but I would like to know if it's true or just really proud owners (as they should be). Everyone bashes Marquees because the are "ugly" to look at and bash AmPro's for fun, even though a 4600 should be able to hold its own against a G90. It's very confusing.
Having gone through all that... Just how much better is the G90 compared to a 9500 Ultra or a 1209/ Cine9, or even an AmPro 4600? Is it really that much better?
If you set up a G90, Marquee 9500LC ultra, Barco 1209s, Cine9, Ampro 4600 (assuming all were in mint condition and set up by a pro and calibrated) would you really see a difference? Has anybody ever used more than one of these sets in the same place?
If it's the lenses that make the difference, could a mod be made so you could hook them up to a Marquee like the NEC lenses?
If my budget would allow it, I'd personally like to get a 9" LC machine (probably a 9500 ultra), but I've never been able to tell by reading all the documentation and posts just how close the best 9" machines are. On paper they all look very similar. One would also assume since Marquee 9500's and Barco 909's are/ were in production more recently that the G90, they would have made some technological steps up over the last 4 years, leaving the G90 with 2004 tech, yes/no?
Cheers,

Hello
A stock G90 is hardly perfect. Sony traded color accuracy for lumens; green is only mildly color filtered and the result is that what should be deep green is more like pastel green. Tune in a golf tournament and the grass looks yellowish. A few G90 owners have swapped in Marquee tinted C elements to get green right. |
To be fair, trading color for brightness is a subjective opinion. Some people actually want brightness at all costs. You can't use that against the G90. | Tim in Phoenix wrote: | | The G90 is several years out of production, Sony has no concern for support, and at least one failure-prone IC is proprietary and constructed of Unobtainium. |
That was too funny Tim, I can't stop laughing. I agree, Marquee stomps the living crap out of the G90 Sony when it comes to parts and service.

You're behind the times. Mr. Mosley, the FIA's resident Nazi sadomasochist, has cut the nuts off F1 - as of next season, the main chassis components, suspension, gearbox, and electronics will all be spec, and the engines will be pegged to the same power ratings. Aero is heavily limited and testing nearly eliminated. In fact, they're locking EVERYTHING down and just making a list of 'competition elements' that the teams are allowed to tweak. Except not during the racing season. From March to November they can't even adjust the fuel injection.
Hell, they're even specifying the kind of pit radios the teams can use now and forcing them to exchange tire setup information.
So, at this point, Indy might leave more room for innovation than F1... 
Anyway, threadjack done. Mosley can blow me.

Doh! I guess I had it coming since I almost hijacked the "call to arm" thread regarding the G90 chip.
Thanks for the clarifycation zGman. I guess I have to keep my eyes open for a modded 9500ultra. Oh look, Curt has it, WITH the piano finish Vidkron case... Now I just need $$$$.
"Vidikron Vision One/Marquee 9500LC Ultra: This set is identical to the Marquee 9500 LC Ultra with a year 2000 build date, with some extras. First off, I’ve added a Moome HDMI input card for 1080p plug and play. I’ve also added a red C lens. These red C lenses are now discontinued, so I managed to get a hold of three new ones, this set has one of them. Finally, the Vidikron set comes with a gorgeous piano black finish fibreglass case that added thousands to the original price of the set. The case is in really nice condition."
AURGH!!! I NEED TO WIN THE LOTTERY!!! I'd even pay Curt to come out and set it up properly... after I buy the house with theatre room to put it in.
Still, for fun I might try blending to PG+'s. We'll see. I guess I'd need another one of those too.
