Nice to hear you're happy with your investment and decision.
What did you mod over the entire projector?
I think you mean electronics by "optical path" not tube face-c-element-lens?

Thanks Julian maybe MP will chime in here but here goes:
Not good with technical aspects but according to Kurt limits have been reached and from
what i can see is this is quite possible. Machine was stripped bare and almost every board
had something done to it and am not at liberty to discuss in detail and if I tried I would screw that up 
12/03/2015 latest vim,neck boards,moomee card all modded as well as power supply,fan mod,green c-element.
horizontal and vertical boards and there is more. If I left something out please forgive me as it was an amazing project
to see first hand. I am running 210 mhz pixel clock 1920x1080P 71.928 custom timings.
I have screenshots of the lizard made famous by others unmodded,modded without green c-element and
quickly converged, and then c-element in with full calibration done by Kurt. I will not post any pictures
as it will serve no purpose and for the first time I have a projector that I don't want to screw with the remote.
I have owned a lot of the projector in the crt world as well as digital and I sell Sim,Sony 4K,JVC,Epson for a
living. This is the most natural slash I am there projector I have seen or owned and I go to cedia every year.
So for what it is worth I can see a spark naturally decay out into a room which is amazing with perfect black level.
I think Kurt said I ended up with a natural no processing 2.41 gamma curve. I sit 1 to 1 on 110" screen and there
is no noise in the image. All image processing is turned off and all I can say the image is real....
Special thanks to MP for making this happen.... Was it worth it????????? Every penny but I will say there is no way
you buy these mods and have them work to there full potential because there is so much that needs to be changed
I counted 9 boards that is not stock. And this is in a 2011 projector.
Mikes screen shots do not come close to what is seen in person.

I asked you about this all because i hoped you did tr board per board.
Like this: start with the stock projector, put in one modded board, notice the differences, put in the next one and so on.
Is that the case?
I could use this info because i want to improve my projectors, to.
I have some info about stabilizing circuits by simple changes.
Done everything "mechanical" (fan mod, green and red c-element, temperature stabilisation via thermal conductivity improvements
between semiconductors and heatsinks, new glycol and bellows and such stuff).
I'll collect some info about circuit level improvements in the next time.
What i don't need is HDMI/moome stuff. My setup will be PC-->projector via VGA (and some hardcore cable).
The goal is to know which improvements are important and which are more like not so visible in the overall picture.
What needs to be done first is surely stabilization (geometry, convergence) then noise reduction.
After that, bandwidth, gamma and fine tuning of everything needs to be done.
And that third point is what I am looking for.
Regards, Julian

The way the mods are designed and work is 3 at the same time or you will not have a reference
video chain. So whats the point of buying the mods. I wanted a noise free projector with reference
black levels and a realism that can only be experienced with the latest video chain. On 2011 projector
and got what I paid for.
I am not a fan boy of MP but respect his work and expertise in the field and is the only one that can make the
new machines work besides Kurt. I wanted the best and bought it. And the customer support is amazing.
As I said before I know enough to be dangerous. I also know what it took to get there and this is far from plug and play.
If Mike wants to disclose this information or Kurt it would be up to them. Thanks and it's great to be back in the
CRT game...

I sent out my neck boards, VIM and CLM to Mike for his mods. What other items need to be addressed to reach the full potential? And if there are other issues to address it would benefit all to know exactly what they are. The reason is that someone may think the cost was not worth the improvement due to the fact that other points were not taken care of. If it is related to caps and resistor mods posted here it should be known. The Moomie card is a must for input on the Marquee and my PC. I am not sure you can select the correct color space in the control panel without HDMI. Like I said, I'm not sure and I have not used a break out cable from the graphics card to the Marquee.

Greg,
Who did your initial set up, magnetic s etc? Your not terribly far from me in Illinois.

After spending the last 12 months playing with mods to my Barco and can say that there is no straight answer to what makes a difference. You may gain 1/2 to 1% on a single change in sharpness or reduced noise, but when you do 10 changes it adds up and all comes together.
You have to respect Mike for the time that he has put into developing his mods. It takes a lot time and money with access to some very expensive test equipment.

Wow, he traveled quite a distance for a set up. Congratulations on your projector.

On a stock Marquee video chain, when the Moome card is inserted, there are three (3) pedestal (black references) involved from source to CRT. After we do the mods, there is only one reference and that reference is the main one from the DAC. Two pedestal references are removed from the video chain completely. And the entire video chain becomes direct coupled (no caps in the coupling) through to the CRT's. These changes here is what makes for perfect black level, because there is only one reference, and it's un-touched directly from the source to the tubes.

Sounds like somebody's taking a page out of the Chris Stephens playbook.
Which is always a good idea.
I would STILL love to have the time and patience to do all the best of Chris Stephen's mods, get the best MP mods, and run them all in my HDMI-input equipped machine. After all these years, that'd still be the state of the art.
I still have my Stephens mod binder. All his notes on Marquee mods in a 3 ring binder.
HOW many generations of digital projectors have our Marquees outlasted already?

Cm you are one of the people that got me interested in crt years ago and just wanted to say thanks  I agree
with what you have said. There is no reason to go digital in fact there seems more to stock up on parts to keep the CRT's
going for another 10 years. With the latest 9500LC and MP's mods there is still alot of life left in these machines. Just when
you don't think the image could get any better with the old tech it does.
Any links to the Chris Stephens playbook or threads? Sounds like a good read...

Have you gotten your boards installed and if so how they look?

Chris basically replaced every single Electrolytic Cap with Wet tantalums. Adds about 30lbs of weight and a few thousands in dollars

I think those are the finest looking projectors I have ever worked on. The image they throw is transparent and spellbinding.

Interesting. I talked to Rocco the other day and he said he recently spoke with Chris and is going to give some of his ideas a try.
By the way, I am talking him into attending Axpona and doing a drive by your place.

There is more to capacitors, printboard material plastics etc that meats the eye.
