Barco 909 (180 MHz) vs Marquee 9500 LC Ultra (150 MHz)

You can have the same lens type on all of them.

P19 tubes may be a little different ?!

It's a setup question (geometry/focus/calibration.....)

No question the 909 becomes really noisy @1080p so you have to use a hushbox or use a headphone.

I really love the fact that you can put nearly any resolution/refresh rate to a CRT.

The Cine 9 is not noisy at all. Its very quiet, and can hardly be heard in anything but the most silent of scenes. Ive never heard a G90 or 9500 so i dont know how they compare. Compared to an XG though, its basically silent.

Stridsvognen, the Barco is superior in that it has a better set of tubes, the astig is better, and itll be sharper right out of the box. I dont believe a stock G90 or 9500LC will fully resolve 1920x1080p, and im yet to see anything here that would convince me otherwise.

180MHz bandwidth might be what Barco claim for the 909, but from things ive read, i find it a little hard to believe. Im sure it can be improved upon to make it that high or higher, but as it stands bone stock, i wont believe it til its been proven. Marquee 9500 ULTRA is listed by Curt's as being 120Mhz bandwidth.

It will beat them for sharpness by all accounts, but i think it could do with abit of work to be all it can be.

I see a hell of alot of praise going to the convergence system on the 909, but in my opinion its nothing to rave about after my experience with NEC and their unbeatable convergence.

Here ya go Cine9 with P19Lug and HFQ900

1080p@60Hz

Maybe the shot is a little bit unsharp but the lines are resolved very well.

Thanks ElTopo.

Looks like the vertical lines are not resolved very well, or is that just the Picture.?

Ideal i guess the horisontal and vertical pattern should look the same, same color and all.

Ill try if i can make a screen shot of my Ultra Marquee tonight.

Not sure where to start, as this has all been covered before.

First, the specs are marketing BS. It was common knowledge that some manufacturers inflated their numbers in the Spec Wars of the late 90s.

As for someone who has compared all three of them, look no further that CIR. Craig compared them in my thread from about three years ago. The info should still be there. Also, I asked tse years ago what the difference is between pjs if they used the same tube/lens combo. His reply was that there would not be a huge difference.

Topo,
That is a good start. Look up a thread that IIRC correctly tse or MadMrH started about this. Tse said the best way to test is to look at the upper left portion of the screen.

[CasetheCorvetteman]

It is a good start yes, but i wouldnt say that is all it could ever be, i reckon it can be made better than that.

Okay, I have learned some things here. New defl. yokes have also melted plastic around soldering points, this is because of the heat during soldering. So Mike this is how the F***K it happened. You even posted a same picture with melted soldering points when you were modifying a marquee with defl. coils of the 909.
I have modded one to see what happened, I glued all loose wires at the outer side of the defl. yoke and gave all inner wires a new layer of raisin so I was sure not one of them could come loose and resonate. Guess what was the outcome when I listened with my rubber tube……. Same little buzzing noise. So this will always be present and can't be changed it's just a behavior of the CRT technology. Normally no one would notice because the fans will overwhelm this little buzzing noise. But in my case the fans are so quit that you are start to hear little other things.
Solution in my case will be isolating cover plate with special computer casing isolation. I think it then will be totally silent after all, without using a hush box.

Mine buzzes like mad from the quad... But time will sort that out shortly.

Let me see what i can do tonight after ive done some more work on the projector through the past few weeks.

Some small improvements for better PQ. Changed RGB Cable that run from boards unit to optical unit with Belden 1694A shielded cable with canare plugs.

Guys,

I installed the Eisemann P19 lug tubes and did a break-in of 10hrs as required.
But I have a few minor issues. After I installed the new tubes a sort of ABL / AKB line became visible (see pictures)
I can’t remember if I had this line on my previous tubes because it’s outside 16:9 but still it’s
within 4:3. Now when I power up my TEST (909) chassis this line is not visible, actually only clean raster.
So I figured that something must be wrong. It appears on all 3 tubes same way.
I switched SMPS, EHT, SMPS2-G2, Hor. defl., Vert, and switcher, driver, port3 boards but nothing changed, line stayed there.
I also reset all settings to mid position and erased all memory blocks. when I adjust top bow,
the lines moves with the raster. I can’t blank it out and when I do raster shift it doesn’t influence the lines.
Hope you can help to get rid of it.

Also another little issue I have (and that’s from beginning that I have these 919’s) is that horizontal sides move a little.
Image is stable in center but it moves a little (half a cm in a sec.) left and right on internal picture and also on source.
It disappears when PJ is warmed up. I already adjusted Hor. width with the trimpot on SMPS by putting RCU on 85
and adjust width to edges of the tubes. Any idea what this could be?
I can swap any board from my TEST chassis incl. good working controller board.

Hope you can help, as you guys always do.
