Nice!!! Hmmm....blend or stack? Nah.....on second though one 10PG is enough.
Hope whoever picks this up enjoys it as much as I am
enjoying mine.

I know but I like my Ecp even though other units can do better
Still wish they would ship(I seen many great deals on eBay but I didn't live close enough to pick them up like this one)
I just can't justifie making the trip without getting the tube faces first
I have been thinking of upgrading to a set with lc optics (marquee maybe) so many choices so little time 
My viewing room isn't real big so a high lumen unit would kinda overkill(but then again I wouldn't mind the extra lumens makes for higher contrast not that mine is dim for my screen)
Right now I am tring to get some fans for my set(one sounds like a bearing is starting to fail(I have a thread about that)
If I do upgrade I will keep the Ecp as a backup(need a good source for the Dallas chip (preventive measure)

Count me in for a free 10PG too  I am very interested in the outcome of transplanting my PG xtra electonics to it...

Its not about the lumens, its about the lux, and how long the tubes will last, given that you must be driving the ring out of your set to get what a 9" would do with the contrast right down

I have explained my theory about this a few times when we talked about the 10PG in other threads, Tinman and others -partly- successfully achieved to transplant boards from PG plus to the 10PG (which is basically a PG plain), gaining finer convergence and focus adjustments on the 10PG. But these modifications never included the transplantation of dynamic astigmatism feature (IMHO which was the biggest step forward from plain PG). This was because the 10PG's focus coil didn't have the winding for astigmatism, but this could have been solved by using different focus yokes, like from barco 808 (without flare yoke?), or even better sony 1292 yokes (with flare yoke?).
But both PG plain and PG plus lacks the bandwidth for 1080 line HDTV signals, while the PG xtra is a very interesting construction from multiple point of view. The basic board layout is based on the older PG sets, so physically transplanting the boards could be easily done, while it has the bandwidth to cope with the HD signals. This is so true that the first generation of XGs almost entirely inherited the RGB path of the PG xtra (while the rest of the machine was pretty much redesigned), this must mean something...
On the other hand the biggest concern is usually the misinformation of the incompatibility of the tubes between PG plain/+ and PG xtra. This is much like the PG xtra vs. XG tube swap problem, it is more like a mechanical problem than an electronic. Elaine Benes and Mark_A_W both posted back then they have successfully transplanted E8508 tubes to PG xtra, they only reported about mechanical problems using them (rotated neck boards, anode cap orientation etc), but in a 10PG chassis there is much more room for modifications, so I really don't think this would be an unresolvable problem. One would ask why don't modify it right away with an XG chassis, the answer is it has way much different board layout, and it is also an often overlooked fact, that the PG xtra is much closer in performance to an XG than to a plain PG, or even a plus. I am sure a PG xtra with 9" tubes would be a really kickass pj, not quite a G90 or a 909, but not too far from them either!

That's all true, and the only reason I used a PG plus when I did this to my PG10 is because I had several of those to scavenge.
And... it was good enough for my needs.
And it IS possible to add the astig coils. It's been done. I just didn't feel the need in my case so never bothered.

Marc, I didn't mean it with any offense. But as years passed people seem to believe there was no other way than how you did it. I seem to recall when a german guy also did his 10PG plus conversion a year ago or so, and I suggested this for the first time, I was almost disparaged for it

No offense taken whatsoever.
I was just saying that I realized this even back then. But you gotta have a spare extra chassis laying around.....
Nonetheless, the PG10 looked pretty damn good.
In a way I'm kind of glad I got out of it. I spent more time trying to improve it than watch it. I think it's a CRT disease.
Since I got the digital, I just turn it on and watch a movie. I let the computer do a full color alignment every once in a while, but that's about IT.
No more endless hours tweaking and staring at patterns. That was the problem with CRT's... they were too mod-able. We never leave them alone and just enjoy the image. We are SICK!!! SICK, I tell you!!

I am just missing the 10PG for the project

I am happy with the picture of my PG xtra too as I couldn't afford a digital machine with matching picture quality, even at today's price -yeah I know I am a cheap bastard
I am still trying to track down the way to extend the bandwidth of it, but that is pure pleasure, not an inevitable improvement. The real improvement would be an LC mod, plus everybody (slight exaggeration) talking about how a 9" XG would look like, the PG xtra + a 10PG could solve this mystery properly

I've used U-ship a couple of times on heavy and fragile items like this. It works well for "pickup only" items because from the seller's point of view, it is picked up (just not by you). Cost depends on how much of a hurry you're in, and how far it has to go. If you can wait for someone who's already going that way who has space on a truck, it can cost less than the gas would.
It works like a reverse ebay listing where you post what you want moved, and shippers bid the price down. As soon as you get an offer you like, you accept it, and exchange contact information. Payment is handled through the site, and the shipper doesn't get paid until you receive your item.

I have the contrast around 5 and the brightness at 3(give or take)and it is close to being as bright as the dlp projector it replaced(but I am in the working of upgrading already  and curt was right about me owning more then one
I will put it this way its better the a digital by a long shot(noise level is about the same since I removed the fan grilles and installed spacers on the fans(they need replacing soon))
My screen is 10 foot diagonal 16:9(slight bit taller as I didn't measure before I made it he he) but I need to redo it soon(homemade screen)
