Thanks I think we are the few who will ever see these kind of Mike Parker boards.

There is some progress here.
There was some problems with the gain of the neckboards that needed to be solved.
Today I watched a part of one of the Hobbit films and man that looked detailed and sharp. Also something incredible happening in the blacklevels. Bad convergence, bad focus, bad astig but already very detailed sharp.
Hopefully it is stable as this is an image I want to see more of

Ok done a reasonable setup so I can judge what I got from Mike.
Mike I do not know how you did it but there is a huge level of extra levels of detail. It seems like there is a gamma boost that shows much more blacklevel information but there is also a gamma boost in the clouds and in the sky. At the begin of Baraka I looked amazed at those clouds that I never saw before. I do not know how this is called perhaps dynamic range but is more dynamic detail.
This also results in sharpness, incredible sharpness. One more thing that stood out was depth. Again I do not know how but the depth was so deep that I now and than felt drawn into the pic and felt fear of heights. Never had that so much before.
This incredible picture that brings out so more information and I think is pretty unique in the world together with the low level of sound the Marquee makes now makes me feel the impossible has come true. When I look at the ugly small Marquee and I compare to the Cine Max it looks as if a VW has just beaten a Ferrari (but with the case on the Marquee might look better)
It was a long wait for these boards but it is certainly worth every minute.

I have one question to the Marquee specialists here. When I did the zone astig on green I found that when I went beyond a certain value suddenly the dot became very wrong and the whole grid shifted around that place. I even had when I corrected one corner wrong that on the other side a horizontal black line appeared. Is this normal or does this indicate a problem with the astig board? Luckily I was able to get every spot right.

Ok I switched back to the Cine max and I do have to admit that there is a different kind of sharpness on the Max. The desktop looked a bit sharper. Strange on movie material the Marquee looked much sharper.
I will do more comparison but the Max focussing system stays impressive. Might try the Barco focus coils on the Marquee soon instead of the Thomson. Also the hfq900 are still on the Max

Still no final judgement. The Marquee has a problem with the neckboards but shows a level of detail that is fascinating. With gravity the Marquee revealed the star nebula in a way I have not seen before.
But the Cine Max has a foreground sharpness that is not yet beaten and that makes the picture look very good too. So I have to do the focusboard mod and maybe the focus coils on the Marquee.
Still it is a feast for the eye to see the levels of detail on the Marquee. I want that with perfect foreground sharpness.
At this moment I could very well life with both CRT's.

I just tripped over a thread from a bunch of years ago where a Marquee that was on a little table about 3 feet high got knocked off (by getting bumped) and hit the floor, breaking the necks of the three tubes and emptying the blue tube glycol into the projector...
How stable is the table...

Where's the link to that ?

Well if that would be my only worry? I had to solder smd components and they break much easier I was more afraid of them

By the way I had expected more interest in a comparison between two CRT kings. Is this forum really dead now?

Let me try and address this, because I think an explanation would make sense here.
I've been doing mods to the Marquee maybe 10 years or more, but one of the things I forget to mention a lot is that the modifications I do to previously owned stock boards cannot guarantee perfection on the resolution patterns. The modification does not replace all and any worn or otherwise not perfect component on the boards.
In your case, you sent me a set of neck boards that one or maybe two were not of the same vintage (the color difference of the connector). And in a lot of previous use, these boards were being used in applications where they were used 24/7. Or in high temperature environments, and this is when we see the two larger resistors showing burn or heat damage to the boards. Though this was not the case with your boards, that does not mean they were perfectly matched or did not have previous issues. I used to ask specifics before someone sent me their boards to try and make sure they could make for the absolute best end results.
The use of the smpte pattern has allowed the boards to be seen in the best matching ability. But that pattern has to be understood in this regard, because these aged boards will not always show perfection. So it's best to understand that unless the difference not subtle, you'll never notice a difference in the image, because your calibration will also compensate for the differences.
And because of variations in other things in the video chain or source, slight variation would be expected. It is also better to have the pattern below the threshold than above, so a slight darkness is better than a brighter line group.
Correcting this problem is always something I'll offer at no extra charge, but the results I can't always guarantee. When I test the finished board, I do not test the set at once, I test each board individually. The parts used are all new and or either 1% tolerance. So nothing I'm putting on the board is ever responsible for the boards not matching.
For the time involved in making the changes to these boards at the price I have to charge these days, one cannot spend three days refurbishing, repairing and testing each board before the modifications are applied. And then go on to extensive testing afterwards.
And we have shown over and over, that some boards behave entirely different when tested on my Marquee.

Yes and the green neckboard seems to be almost perfect allthoug somewhat low in gain and I absolutely agree that it is not in the modified components so it must be somewhere in the board. Perhaps Gjaky's problem is related as he has boards that just do not perform while the chips should do it. Very strange.
But I am absolutely honest that with very good red and almost perfect green the image detail is still shocking no doubt about that.
In fact at this moment I am more worried about the focus system than about the neckboards. I hope to test soon and I hope to completely beat the Barco on all aspects!

Oh and absolutely the time involved to fix the problems is huge and there is now way we can pay for that. Thanks!

I'll also send you some small inductors that will allow you to also do to the Stig Amp board, what we're doing to the FGM. This will also improve focus

Thanks! I know I will get there.
I also have Sony and Barco focus coils to try but with Barco I have to figure the wiring. If you know how the wiring should be done with the Barco coils I am very interested in trying those too.
But first the boards.

I have the 909 coils on mine. But would need to find the pictures if that's what you're trying to use
I'll also post one day on focusing with the Mods. You should never use the internal test pattern to focus if using 1080P as your source.
You'll need a point&shoot camera and tripod. The cameras are cheap, and if you can get one that has manual focus that would be better.

Ok. I use an external pattern but I had trouble seeing anything change with focus on the left and right edge.
I have a camera and tripod.
If you could make a picture that shows how the 909 focus coils pins connect to the marquee wire colours that would give some assurance.
