Dave,

$180 for 1 - 4 years, you telling me most bulbs are only $180 and last up to 4 years? Damn, last I heard people were saying the bulbs for the JVCs, Sonys etc were more like 4 -$500. $180 for 3 years lets say is very reasonable for the enjoyment you get from the PJ. But I still have the problem or should I say the bulb still has the problem of loosing it's brightness and it's starting colour temp/spectrum so often. Or am I wrong about that?

How often do you have to do grayscale/gamma tuneup on these bulb PJs?

Isn't there some kinda forum where digital converts like Dave can go and annoy
other digital owners, and leave the rest of us who like crt happily lost in
our delusions of satisfaction and enjoyment ?!@?

why get annoyed? He likes digital...he's ok, you're ok.

He probably likes crt too...

zGman,

I was kinda thinking the same thing. Dave means well, and starts off sharing his extensive knowledge of CRTs. All is good. Then someone has to go and make a contentious comment that "if you're a poor bastard, CRT is a vastly better deal." That's all it takes to light Dave off, and the newly converted apostle climbs on his soapbox and starts spreading the new religion. Before you know it, we're having the exact same ana vs. digi discussion in every CRT thread.

The sad thing is that he's (usually) fairly accurate in his assessments, and is only trying to correct some misconceptions that arise because the times are changing. But I already got it. You probably already got it. I don't really need to hear the same sermon over and over again, and it gets kinda old. It's kind of hard to fault Dave for it, because he really is trying to be helpful, and he's not indulging in bashing. But the worst part is that before long, we're no longer talking about CRTs anymore. And that's the main reason I come here.

I recently had an opportunity to pick up a lightly-used Optoma HD7100 (the wunder-digi-PJ that brought about Dave's conversion) with <100 hours on the bulb, for ~$550. So Dave's point about affordability is accurate. I passed on it, because that's not where my interest is at the moment, and I'd rather put the time and money into CRT, or other aspects of my media room. The CRT I already have is plenty good enough to satisfy me for a number of years to come, and I don't feel any need at this time to make a switch to a different set of compromises (yes, neither is perfect ). I'd really rather read (and contribute to) discussions on how to maximize that resource.

The only solution I can think of is if we can avoid drawing comparisons with digitals, then Dave won't feel compelled to jump in and shatter our delusions. I sure don't want to chase him off... even though he is a bit of a pariah now. I think he still has lots to contribute on CRTs. So let's just discuss CRTs as if digitals didn't even exist. Maybe that'll work.

I got my Barco 808s 4 years ago, $400 at that time and it put me on the road to crts, it is very quiet no one has ever complained about the noise and its table mounted I would not think you would need to change the fans. I also put coloured glycol in it which I managed to get from some cheap tubes on ebay. The glycol makes a amazing difference set it up then watch a few movies without it then put the glycol in, the glycol change is easy on these as well.The picture is great with blu ray hd dvd etc, at that price I cannot imagine getting a much better deal than you got, once I get my Ampro 4600 green tube fixed I should be able to compare the two although one is ac and one lc at least I will have a reference point. Very good buy that pj, should keep you quite happy for a long while.

WTS commented:
> Another thing I did was remove the expanded metal piece that fits around the lens to allow more air flow from the front. Then I covered the side vents which cause the air flow to come from the front around the tubes/neckboards then exhaust out the back. ...after about 4hrs running the (exhaust) temp was well under 30C. <

Those sound like good things to enhance cooling, Walter, but I have to wonder why'd they do it? I.e., if perhaps the metal pieces were there specifically to throttle air-flow, or create a pressurized environment? And the side vents to ensure that whatever is in proximity to them gets a separate cool air feed?

If not, I wonder why they'd bother to go to the trouble for either, since it would be simpler and cheaper to just leave the side vents and the metal pieces out. You see what I'm saying?

Good numbers to have. Thanks, Dave.

What do you think of the concept of starting with a really bright PJ and putting a ND filter on it to tone it down. Then when it falls to say 80% of its original output, removing the filter to extend the life span? Any merit to that for folks that might use their PJ more than you? Or are all the better digitals lower output to start with?

I know of at least one digital guy with a DaLite HighPower screen, who purposely mounted the PJ higher, then lowers it for more gain as the bulb ages.

[benareeno]

I think in most cases an ND filter is a must with most digitals.

Also, crt for me...simply throws a better pic. Digital throws a better pic for some...I can't argue it. I've owned several projectors of both types. I usually ditch crt because of htpc and or the noise of the projector. I usually ditch digital because it's too expensive and there's something I don't love about the picture. I really love smoothness...and nothing is the equal of crt in that regard.

Thanks, Ben.

I have no intention of ditching my CRT any time soon. But I do like educating myself about options when I have the chance.

[nettwerkjohn]

Well, aside from the loss in brightness, the Ruby hasn't changed color temp. Its 18 months old now, still on 1st bulb, 1800ish hours.

Xenon is really the only way to go for digitals.
