I got a new green tube from Greg Eisemann for my G90 recently and finally made time to install it and do a first pass calibration.

Wow.

The green tube I had been using was relatively low hour and showed no wear, but what I didn't know before buying the projector was that it was not an LUG tube but rather an LCP. The difference in overall picture quality between the new LUG and old LCP is staggering.

When I got the G90 a couple years ago it took me a while to discover that the green tube was not a LUG or LQF. After a lot of effort trying to get the EM focus dialed in I never was able to get the green to focus as tight as the red - close, but never quite as tight. Once it was revealed that it was an LCP it made sense that it wasn't user error on my part but the larger aperture in the electron gun.

The new P19LUG Boeing tube I got from Greg Eisemann is amazing.

After letting it wear in and getting the mechanical alignment and optical focus set I made a quick pass at the EM focus. Scan lines, super easily, right away even up in the corners. It brought a tear to my eye.

I reset all the registration values and setup the geometry from scratch. Everything fell into place and it was great to see the red and green overlap without the green bleeding out on either side!

The new tube also has the more correct green c-element, and doing the HCFR stuff showed that in the CIE chart right away. Getting the grayscale dialed in actually has me using a lower Gain value for green than I had before - which I guess might confirm some of the observations people have made about these tubes being a little brighter. I was expecting to have to bump the green gain up or drop the R/B to compensate for the new c-element but that wasn't the case.

Another thing that was obvious right away doing the color calibration was how smooth the new green was compared to the variation in phosphor grain the old one had. From a distance white fields looked white with the old one, but when you got right up to the screen you could see how much small variation there was in the green phosphor grain. The new one is super consistent and smooth, even when you get right up to the screen.

After doing this first pass setup we had some friends over and watched Slumdog Millionaire on Blu-Ray. I've seen the movie before, as had my wife but it was new to our guests. Before we watched the movie my wife had teased me a little bit about having put a lot of time and money into replacing a green tube that looked perfectly fine and our friends who had been over to see lots of movies also said they never thought there could be that much of an improvement over the way it had looked before. When it was over, they had different things to say It looks so much clearer now!

Huge thanks to Greg Eiseman!

The projector has always looked very good, and I was hoping the new tube would be an improvement - but my expectations have been significantly exceeded.

I'm a very satisfied customer and would encourage anyone thinking of getting a tube to talk to Greg.

I got a green P19LUG from Greg as well, it is no surprise that it is the only tube in my 1209s that I can pull in visible scan lines at a severely compressed 1920x800p 2.40:1 raster( vertical size on 03) my other 2 tubes are P19LUGs as well and they are razor sharp but this goes to another level with this green from Greg

Gregs tubes are special and they are not at a special level price either, very very pleased here as well

I am also very impressed with Greg's P19lug in my Runco 1100. It is extremely sharp and of all this tubes I have installed this one "dialed in" the most easily.

I have to agree with you. I'm very, very impressed.

Hi,

The tubes I get are hand tested and have a special gun made for flight simulation.

They have a very small beam width compaired to a standard P19lug.

They are a little more expensive but worth the extra $150 dollars over the Chinese made ones my competitors are selling.

Benefits of Simulation grade

-No Phosphor failure
-Brighter
-Better Phosphor hard to burn
-Tighter Beam
- Less break-in required
- Finer grain Phosphor for a smooth detailed image

Let me know if I can help you. We have never had one ever returned.

My Tube supplier now has a better sharper replacement for the P16 8 inch tube.

Its supposed to be 40% better.

If anyone wants to do a review let me know.

You can't fit PT18s to a G70, they are a thick necked tube.

So are the P16's Greg is talking about above I guess, I was just TRYING TO MAKE A POINT ABOUT CORRECT TUBE LABELLING.

I "think" Gregs P16's are the long/thick necked Barco/Marquee versions not the Sony/XG shorty's?

Email me on the G70 tubes on my website

The P16 is too large to fit but they most likely have the one you need.

I can get tubes quite cheap now as they are stocking up.

Hey Greg, do you carry any lower end tubes? I need a 07MSP for my Sony 1252.

Thanks Greg will do,

So the G70 (P16/08's) you Can get hold of offer the Same Higher performance as the
Sim Grade 8"Tubes you are refering to ?..

I can have one made for you.

Email my website for information.

Cost will likely be aprox $1100.00

If they have some in stock I can get cheaper.

I hope that helps

I'm hearing great things about the green simulator LUG, but are the red and blue versions equally as sharp?


It'd be hard for me to justify spending the money as the LCPs in my 9500LC have under
400 hours on them. They're new for all intents and purposes. But I will admit, as
my quest is always for higher resolving power, and I've done some cool stuff to get it,
I wouldn't mind scoring a set for myself. Too bad it's a luxury I really can't afford or justify at this moment.

Maybe Obama will give me a set?

OK, here's my stupid question for the day. Why are you guys so horned up about more resolving power than the LCP's can produce? I know for a fact that LCP's can produce visable scan lines on a 100 inch screen at 1080P from a normal seating position. I don't want to see scan lines any more than I want to see screen door effect. I would have to de-tune the projector to make it watchable.

Because it's never possible to have too MUCH resolving power, but it IS possible to have too LITTLE. And, if your machine can EASILY resolve 1080p, it gives you a little leeway to have an IMPERFECT setup and still resolve 1080p. If your machine can JUST make 1080p, then the setup has to be perfect.

Personally, I'm hoping for 4K, someday.

That's a crock. Let me get this straight. You'd rather spend 3K+ on a new set of tubes so you can do a crappy setup and still get a decent picture?
Good luck with that I'd rather save the money and invest in a couple of more hours to tweak the original tubes.

For the record, what per cent increase in focus should you expect with LUG's over LCP's? If you tell me it's a 100% increase, I want what you're smoking. If you tell me something more realistic like 5% and you're willing to pay 3K+ for it, I still want what you're smoking but you can pay for it
I still don't see the point in having more resolution power than you can see from the normal seating distance unless it's for bragging rights. Let's just whip it out and measure it

Hey, if I'm going to buy a spare set of tubes, I can get these hand-selected LUGs for just a few percent more than a set of LCPs from VDC, and probably cheaper than LUGs from VDC. Why not get the better tubes?

We all know that setups drift with time. You could get a 5 percent drift in your setup
with the hand selected LUGs and still be able to fully resolve 1080p. But you may lose
your ability to resolve 1080p fully if you experience just 1 percent drift with LCP tubes.
(Speaking figuratively, not actually trying to say those are the actual percentages.)


The difference is how often you'll have to tweak your setup when its resolution capacity
has degraded due to drifting.


Regardless, if I'm going to pay for new tubes, I'd pay a small premium for better tubes.

The simulation LUGS are very sharp and very bright.

The glass is very straight so you can get the corners dialed in better.

I have no problem using them and they don't drift on any unit I have used them in. At 1080p they are a must the LCP will never do 1080p from my testing.

I have never seen a LCP do much over 720 with good results. You might see scan lines but it wont resolve the fine details.

If you need LCP I can order them from my supplier. They are cheaper aprox $700-$800?

Have to check customers always want simulation grade LUG.

Please send to website

[email protected]

my inbox is full

IS that the G70 tubes?

My reply was since the neck is smaller I assume they use a different gun.

That being said the simulation grade gun used in the 8 inch P16 and LUG wont fit.

So I assume the G70 tubes will be the same resolution as the original.

You are welcome to test one and post here. Since you post I can give you a discount.

I hope that helps
