Isn't the RGB path of a S model very similar to the 909? Same switcher and quad decoder but different neckboards?

Now that's not a 808 anymore. Also I had graphics S model so with 120mhz amps.
After that I got for some months a 1208s Also liquid coupled with 8' P16 tubes but with 9" LC housings colored c elements and HD10 GT17 lenses, but still the sharpness that I have now you can't get with a 8" I think. Also the bandwidth is much better, less banding or ringing on left side. |
That is also what I think.
But this isn't a 808 no more, and with the new simulator tubes that eats original tubes for breakfast, and with new mod that has 3,5GHz not 700Mhz like the original, and everything changed. I am not so shore, but I have to see it before I say something more.
And I Have seen many 909 and cine9 before. And it will be interesting to see.
The best is that its much more punch in the projector and still holds the ansicontrast quiet well after what I have seen so far.
And that sharpness is close or better than a 909 I do not know for shore, but I will see that when I get there.
Just for fun, so I have something to compare just sharpness. Take a photo of the nec pattern just as the HW55 picture I put up here on this site. You have to download it. Then just as many nec in black and white like that picture. since I did not take the photo of the 808 nec pattern I need to take it like I normally do so it can be compared. This is just for a indication.
And I know that you have a sharp CRT.
Do that 
Here a link to the pattern if you do not have it.

I had a 808 with P16 tubes and HD144 years ago and this was superb in sharpness without mods.
It's all about a good setup i think.

For all we know here this can be a rubber duck. Nobody have seen any pictures of any of the mods tubes lenses or anything.
Why not just consider the thread a scam. If not im sure the starter would have addet some documentation.
Do BARCO use HD144 lenses on LC projectors.?

HD144/145 is an AC lens, not LC.

Barco used HD117 and HD215 LC short throw and no colored C-elements.
Scam? I don't know but I agree that it would be usefull to have some more information.
And still I think you can't compare a AC modded 808 with an 9" 909. For example I know that a AC 808 have a lot of halo issues due to reflections which will influence contrast aspect ratio.
I think the best comparison would be a modded and not modded 909 side by side or with or without mods in same HT and footage with same camera same source etc, etc.
Then we could really tell if there are improvements in: Picture noise, BW, ghosting, banding, ringing, color and gamma.

Yes a scam you said it. Nice sayed.
The lenses fits the 808 g well.
But with a bracket it fits perfect.

Unless Greg does make his fully custom and all original boards for the barco the 3,5GHz bandwidth is bs. even in the preamp section... ALL circuit boards in consumer electronics made from the FR4 material (or worse), that is only usable at frequencies bellow 1GHz, that is a fact, over that the board itself simply eats the signal. Greg who has so much experience with microwawe circuits really should know this...

And still we will need a skilled guy to evaluate both, so it dont come down to setup isues. or other differences in magnets and stuff. And needs to be a 909 with new lug tubes, and the best extern HDMI to RGBHV converter we can find. For both machines. Or put the same HDMI bord in both.
Calibrated to same measurements.. Native CRT ..No Radiance corection or funny buisness. And then swap boards, and see if differences follows the different boards.
The way it looks from here is still a SCAM.. Someone trying to sell upgrades to a projector thats given away for free in most of the world, and the end price is higher than any high end 9" CRT you can buy today, with new lug tubes.

Do not look good I agree. But I need to see it.
And the guys that adjusted it have done a super job I'm sure. But picture can lie. As you know.
And again you do not watch test pattern you watch movie. And that is what i gonna luck at. But control test patterns.
The calibrating is not up to me. That need to be done by a professional with hi end equipment. Not calibrating for kindergarden.
I have the pictures from old mods with wrong focus jokes and spoles and deffected Video card now also new upgraded installed. To be a almost fully 909 just some parts that also gonna be installed as they say. But I do not care.
I take same pictures same distance same camera. And shutter time and adjustments. Then I get a indication. And it's much better than last time.
But in a 909 or marquee9500 lc ultra do not know. And we newer find out. Then we need a side by side test and not possible.
To far to travel and to much to carry hehe.
Good night

Well he says and post many things even when he have no clue on what he messes with. Or have seen or checked some before posting.
Just 3 letters LOL

Exactly, and that is where the 9" machines are going to be vastly superior, the AC lenses on the 8" will wash out the darker areas of that fine black text.
And i thought Barco fitted most 808s with HD-8 lenses.... If so, they are hardly in the relms of HD-144/145...

You "think" it is? Unless you can be sure, we must assume they were the factory standards...

From what I can see the 909 is more closely related to the BG808s than it is to anything else. Thats why I used it to build what you see in the image attached.
