|
|
I've been seeing a few Sony VPH-G90's for cheap lately and I was wondering would it be worth getting one and re-tubing it? or paying 3-4 hundred to ship one. As I've have very limited CRT experience mostly with Barco's I know nothing about the G90 as it has been to expensive for me in the past but now they are more affordable, I just saw a reality 909 go for $1500 on eBay, untested but I think still a great deal.
Any "what to look for" info on the VPH-G90 would be greatly appreciated.
One I have seen the seller says it needs a new green tube.

You need some time for sure to set it up properly.
But if you can get a high end 9 inch maschine for low $$$ it's maybe worth it.
Up to you

I just bought a G90, and as i already have a few Marquee 9500LC, i was curious to see how they compare.
It is the most expensive CRT i have ever bought.
On top of that i also think its performance is way overrated.
Its now stored in a corner, and im back on my marquee, witch cost me much less, spent some money on mods, and bought a few spare machines, and still cost me far less, and performs much much better.
I think it all depends what kind you are, and what you will prefer.
The G90 is the most plug and play machine, with a medium performance, you need to be carefull what input cards you buy for it.
LUG tubes are expensive and no better than the video chain.
The Barco 909 seems to be the hi end CRT with most problems, worse video performance, and on top of that also the most expensive to buy parts for.
The Marquee is cheep, it has the best video chain, parts are cheep, and if moddet right it will spank any other CRT ever made.
Standard it needs some know how to get it setup to perform right, and know how about different boards, and CRT types.
Biggest problem is if you get a old 3D machine with P22 tube on green, other than that the rest is mostly cleaning and fixing a few ground connections.
Tubes are also easy to find for the Marquee.

There's also a Marquee 9500LC for $1300 obo not too far from me. Seems like a better choice for me to step up to 9". The picture shows MARQUEE 9501

Let's face it, AS IS CRT projectors have been dead in the water for a long time.
I will debate the point with Stridsvognen, a stock g90 is far sharper than a stock 9500 Ultra, although with LUG tubes and high end lenses, my guess is that the 9500 come pretty close. Still, given the option of modding a 9500 for LUG tubes vs a g90, I'd take the G90. For me, if I were to buy a set for personal use, it would be the 909 first, the G90 a close second.
That's the fun of CRT though. Like high end audio, there's no 'right' answer, only opinions.
As for an AS IS G90, unless you know the exact tube condition, hour count, etc, I'd pay no more than $500. IF you know the tube condition and hour count, then maybe up to $2000 if there is no or minimal wear on the green. The extra $500 I get for the low wear G90s that I sell is literally for checking it out, a new Dallas chip, and backing it with a warranty. I sold one late last year to a customer that installed it a month ago, and sure enough, the Ya board packed it in within a few hours with an 88 error code. I covered it under warranty for him, as he's a good customer.

Curt..
Have you ever seen any of these latest MP high bandwidth mods.?
Justin have one, and i know many others have them.
You have loads of Marquee tubes, and parts, and Marquee machines can be found for free.
I cant find any reason why anyone want to use a LUG tube if they dont have bandwidth to resolve a HD image.
If you want to see something cool, then get a set of the latest MP boards for that Vidikron you have there, and ask Mike to mod a Moome card to.
When you have seen what a Marquee with a clean high bandwidth video chain do to your screen you will think that the G90 and Barco 909 is AC machines.

The G90 has 6000+ hours and the burn on the green tube shows up on the current install, it has a moomie hdmi and 111" viewteck screen asking $900.

Well, figure you'll need a blue and green tube at minimum.

Strids- no, as a rule I don't do A/B comparisons, I just don't have the time (or real interest) in that. I leave that to others here. One day... I will stop posting that I will actually put together a home theater again..and I'll actually DO it! Then yes, I will experiment with lenses and sets.
Just based on the extra amount of adjustments on a G90 and a 909 compared to the Marquee as to focus and astig, I'd say that both those sets are sharper than the 9500 Ultra. I have seen a difference while setting dozens of all of these up on the bench as well.

I'd probably buy a G90 right now if I had the means to go and pick it up. I've seen them in action and overall I think it was what I consider an ideal machine for someone as myself. I'm not really into modding out a projector, such as the marquee would require to make it really something. If the G90 indeed was a bit lower in performance, that wouldn't bother me. The design and ease of use are what attracts me to the G90 specifically.
As for a Barco 909, I would bet that their performance is also up there, as the few barco display products I've had are simply in the upper category of quality without even questioning it. Any projector will have their faults and failings, but I think as someone mentioned earlier, its really a taste of what the projector owner wants out of the projector. I wouldn't say any are better than each other, they all have their positives over each other, and their negatives.

as for the reliability of the 909s, I put them on the same level as other sets at this point, having worked on enough of them now to know them. It was the same 'afraid' factor I had of them as I had with the g90s the first time I saw them... not having worked on one, not having spare parts, etc put the fear in me to even get close to one. Now I have backup parts for all sets, and know both the g90 and 909 well enough to be comfortable around them. Service on either.. not an issue.

I understand you, and know what you mean, i just think that horizontal sharpness dont hold much value to the overall picture performance, as we all know they dont have the bandwidth to make any vertical resolution.
I asked Mike about both the Marquee and G90 video chain, and im not sure i remember 100% correct, but it was something like the Marquee have 8 steps to pass in the video chain, and the G90 18 or something like that, and this is where the power of less is more.
Every step makes noise and distortion, and that washes out and mutes the output.
This is all based on my testing and experience, where i play with the standard Marquee and Standard G90.
And then a moddet Marquee and a moddet G90.
Lenses and tubes holds close to no importance in this comparison, as sharpness is not really what i have in focus, its something i worry about if and when the projector resolves horizontal and vertical resolution identical.
What ill have to do is to run a set of LUG tubes on a clean high bandwidth video chain in the Marquee, ill guess the spot will be to small resulting in to dark image and lost punch.
The LCP tubes can draw scanlines running 1080P 72hz, and i dont see that a scanline gap will benefit anything on screen.
I see where the G90 fits in, for those who just wants a fast setup, and dont care to much about a clean high contrast image.
If money holds any importance, a G90 is not free, often needs new tubes, and LUG tubes, they dont come to cheep.
A Marquee is easy to find, comes from free to cheep, tubes are easy to find, cheep, not very often needed, mods can be found, not expensive, and the end result for sure leave others behind.
I dont think the Marquee is easy for any one new to this, but for someone like you, its straight forward to make a Marquee with new LCP tubes and a moddet 03VIM, 3 moddet neckboards, and a moddet Moome card, and you will be able to resolve 200Mhz+ as sharp or sharper than any of the LUG based projectors, who is fighting to display a 100Mhz bandwidth.
Later ill follow up on the performance of my G90, with a MP BA board, and neckboards + a MP moddet V3 Moome card.
That setup will cost a total around 4500$
Ill compare to a Marquee 9553LC Ultra with HD10E lenses and full MP 300Mhz mods, a new green tube, who have cost me around 2500$ total.

Together with those words, maybe part pricing needs attention.
Am i wrong if a G90 YA board cost 1000$
LUG tubes prices ? And how many hours do they last?
And whats the prices for the most common 909 boards who fails, or repair prices.?
The Marquee 9500 and 8500 share boards, and as many 8500 is given away for free, i think that board and power supply prices will be very low.
At least i think that holds some importance, as Jeremy112 writes, he would buy a G90 if he had the means.
It looks to me that most of those buying CRT today, just dont have whatever kind of money it takes.
Curt if you would offer the service to install and test the MP mods in Marquee, it would for sure be the best deal, but you will have to get used to that today the main limitation in a CRT is not tubes and lenses, but the video chain.

Finding spare parts for a 909 for a good price today is not a big problem anymore.
Maybe the controller is the most critical part ?

so you passed on this? I bet if you showed up with $500. cash the guy would take it. you don't even have to worry about shipping . Both remotes, ceiling mount, kind of a rare deal to find this local.

define good price? yes many places that have them are starting to get rid of them, planetariums and such..but still I thought the parts are not that common, give some examples of prices that you have spent on parts for a 909.
marquees are ridiculously cheap, "local" fellow was selling some older complete projectors, he had 8 or 9 of them at 50usd a piece but got no takers in a long long time..I thought about picking a few for spare parts but I already have way too many crt+s and wife is bugging me every week to get rid of them..

So I ended up with a NOS Marquee 8500LC hence the new post. https://www.curtpalme.com/forum_archived/viewtopic.php@t=36370.html
If you would've asked me if I'd ever have a brand new $30k when new CRT ever I say never happen. Thanks to who ever purchased it new, sorry you never got around to setting it up.
