I have Barco 909 focus coils on mine. They're better, sorta like the Sony 1292 coils. I didn't like the 1292 coils and I'm not that fancy over the 909 coils. I'll just rather leave them in there for now.
The HFQ900 lenses are what you would want or need for blending. They are designed with blending in mind. that's what's on Williams Blend setup, and they are flawless on his system. Some say they're the same as the 10F found on Sony's. They're not. The 10F are older lenses, while the HFQ900 (10E's) are the latest designed high end CRT lenses.
The LUG's and the HFQ900 are believed to have been designed specifically for Barco for the 909.
The HFQ900 are the first set of lenses i've seen that does not have the outer area distortions (rings), that are so common from CRT lenses. And that's what makes them perfect for blending.
They will be the next set of lenses I'll be getting.
Yesterday while Craig was here, I was able to show him how sharp text were looking directly into the tubes, but that was not he case on the screen. I'm using HD-10L lenses, that i was somewhat content with until I noticed they're not that good at 1080P.
The Moome 1.3 is a different unit all together over the 1.2.
The 1.3 is the first device like this that I've seen that produces FULL dynamics. And it has an excellent color range.
1.3 and 1.3v2 are similar, with the only difference (that I know of) is the upgraded gamma circuit and the different filters that it now has that improves the sharpness in the image. The 1.3 is a real improvement in the colorspace issues these units has had from day one.

My vote is for the Red C element and while you're at it add a new bellows from Nashou.
Let's not forget the Vidikron case. Guaranteed to increase performance by 200%... honest...

I forgot about one of the most important mods you can do. Have a professional calibrate it! Chances are the difference would be huge even without mods. I wish there was someone near Calgary that could do mine, but I want to get a new Green and Blue tube first.

I know eh? Total yawn fest.
Ok, don't even set up your projector, order every mod out there and do them all at once... now that you've f**ked it up royally and have no idea what caused it, post a "please help" thread...
More interesting?

All I have is a lowly AC 8500, but from my limited modding experience, Mike's latest 02 VIM is #1 . I've never had the privledge of witnessing a stock 03 VIM so I cannot comment there, but this newest VIM blows my stock 02 VIM away, and all of my supporting mods are not even complete yet.
The MP modded VIM is followed by the color filtered HD-144 lenses and Barry's adaptors. I saw a significant increase in sharpness top, bottom, left, and right along with a drastic upgrade to the colors. For those who aren't lucky enough to be in the LC world, color filtered 144/145s are a huge upgrade.
#3 would be the dragan mods. I did these myself, and for the most part did not see a difference in picture, most likely because my pj wasn't as tired as I thought it was, but I did see an increase in stability, especially to convergence. Well worth it if your have an older Marquee that has some hours on it, in my opinion.
The rest I don't have experience with (yet). I'm on the fence on the HVPS mod. I saw a few posts from Scott where those carbon comps are there for a reason. I'm hestitant to change them, but it may be worth the gamble if there is that big a difference in background noise.

The carbon composite resistors are no longer available or almost impossible to come by. So they should only be replaced in a HVPS where they are defective. The later version HVPS uses a different type of resistor I'm not sure what type it is.
If there's no real reason to replace the composite resistors, it's best to leave them alone.That's one circuit it's not good to randomly substitute parts in.
An un-modified 50-2035-03P (03 VIM) is a higher bandwidth VIM compared to the 50-2035-02P (02 VIM). So that's why it's known to be sharper. That extra sharpness also shows up more noise, so it's also an noisier VIM than the 02.
I wish you lived closer and would be able to come and see when I compare a stock 03 VIM to a modified 02 VIM. I'll run a series of test, but the noise and bandwidth test is what I want to focus on during the comparison.
And you have the VIM only.. I have to get two more testers on board hopefully soon, and from there we'll move forward..

Far be it for me to stir the pot, but I feel I must.
I know Scott probably hates when I bring him into a discussion, but he did test the frankenyoke mod. IIRC he said it was of benefit only when you are running the contrast high.

- According to Mike my boards were close but not quite "Mikron" boards. I had an 03 VIM and neck boards that were modded by Mike. I did a number of comparisons between unmodded 02, unmodded 03 and the modded 03 VIMs. The unmodded 02 was the clear looser of the three, but the unmodded 03 and the modded 03 were indistinguishable.

You had an 03 VIM that was an earlier mod version, that I had attempted to upgrade to an Mikron but was not able to do so because at that time I was using potting material. The neck boards were also earlier version, and were NOT upgraded at all. They were not Mikrons. I also informed you that the version neck boards that you had was not going to work well with the Mikrons.
So what you had was an improved earlier version modified 03 VIM that after working on it, I let you know I could not make it a full version.
I'll be doing a TRUE and better comparison of the boards you mention soon. But before that happens, I'll just like to say first that there's a huge difference between an un-modified 03 VIM and a modified 03 VIM.
And the difference between an un-modified 03 VIM and a modified 02 VIM is substantial. And that I'm going to also prove.

While Craig was here this last Sunday, he touched up on my color balance using his spectro-thinga-gismo..
I genius of a guy. The guy has to be in the top two in this field. I'm still blown away by the depth of what he understands about what's going on in the image. And his degree of understanding the technical aspect of what happens under the cover of the technology.
1080P into my lowly (02 VIM) Marquee 9500LC - 100% UNTOUCHED!

What is your screen size ??
HD-10L's focus very, very well, but ONLY on very small screens. The absolute maximum is 72" wide, I believe...Their size limitation is a very *hard* limitation, above it and they simply don't work.

My screen width is 82" - It's a perfect size for the 10L's.
When looking directly into the tube, the image (text) was sharp and uniform over the entire raster area. On the screen, the sharpness diminished from the center out to the edges. This was something I've been aware of since my commercial days, but was not so aware of it until recently.
What I've noticed after looking at it again. The lenses (10L's) dod not handle 1080P too well on the outer edges and anything going away from the center.
I also have a set of GT17 lenses, but they are not best suited for my screen size. So based on the lenses out there and which would be better for my screen size, It would be better for me to go with a larger screen and that would allow me to go with better lenses.

Oh, I forgot to mention something I showed Craig while he was here. We had the 9500 warming up showing DVE.
I had my contrast set where I usually watch it at 50 or 53. I then cranked the contrast up to 100..
With the test pattern on the screen, I think we saw blooming or bleeding at or above a contrast of 90... yep, it can get very bright and still maintain the 1080P resolution.

But is the contrast actually putting out the same lumens mike compared to a stock VIM? I know you removed the one chip for the edgeblend contrast on the vim and used inductors to tie in the missing link. Not sure what else you did there but could it possibly be attenuating the contrast to not be as much a change as a stock vim. So i what i mean is could it be acting like the Green Drive control does, a large number change on the slider is really only a small change compared to the red and blues drive.
I just cant see how it would allow it with out altering the amount of current to the contrast at the Neck board. the vim can't control the spot size of the beam, only a focus adjustment, astig control or a tighter magnetic field would, am I correct in the physics of this? Can you measure the voltage on the vim test points TP14-16 , the range should be from 0-8.5 volts(0-100 contrast) . I'm just wondering if you may have lowered the max output here inadvertently not knowing.
Or measure the center pin of the video cable it should be 1Vpp at full contrast.
