Thanks, now we know whose house to raid when the bulbs are all gone
Are you kidding? That is my daughter's post-apocalyptic dowry!
Edit:
I would accept a nice game in trade though...
Arcadeshop.com no longer carrying 19'' CGA CRT's ?

I read the gospel from brother Tighe and decided it looked like
crap under a "New" light bulb. I've always hated those CFLs.
I've joined the revolution... ~ 100 bulbs should keep me comfortable
under the warm glow of incandescent light for years to come.
Preach it Brother!
I'll pick up some more when Walmart restocks. Picked up 100 and 75 watt bulbs.

Yea they dont really have to many thrift stores in Central NJ either.. nearest
one for me is a salvation army 45 mins away.
There has to be a bunch of 19" tvs sitting in a warehouse somehwere near us.
Everything has switched over to the dam private electronic recycling places
in NJ. You can 't throw out electronic stuff in NJ in the trash anymore.

Its to much of a crapshoot trying to buy them off craigs list one at a time.
I'm not sure what to do.

Eventually modern display will be able to emulate raster and vector CRT displays, but as far as I can tell, we aren't there yet.
There won't be a push in that direction because that is not where the market is.
I'm wondering at what point will a classic game collector decide to purchase obsolete manufacturing equipment and start reproduction on tubes.

Around here thrift stores won't take old TVs anymore. Given the HD transition, coupled with the cost of disposal, I can't blame them.

Right now, CRTs are still plentiful enough that there isn't any real demand for LCDs to go in older games.
But as the CRT well runs dry, that demand will rise. And arcade-intended LCD panels will be made. We'll start seeing 4:3 panels in 26" and 33" varieties with native resolutions tailored to arcade resolutions. And they will look DAMN good.

Unfortunatly I am going to have to bet against you. I think the days of 4:3 panels is long gone as well. LCD manufacturers.. which there only a couple,
are totally focused on widescreen formats.
I highly doubt the 5k active (a guess) arcade collectors are going to
be atractive enough to make anything custom.

They aren't. Unless something happens to the technology such that making a custom panel becomes easy and cheap, we aren't ever likely to see 4:3 panels again, let alone ones with precisely CGA resolutions. (well, I'm sure you can get custom panels right now, but you don't even want to think about the costs involved).
Unfortunately, in the LCD arena, the best we can hope for at the moment is panel resolutions to rise to the point that we can fake the fuzziness of a CRT (you might need to be even higher res than Apple's Retina displays to pull this properly).
We need a solution that re-purposes commodity items to create a usable replacement on a reasonable budget. I just don't know what that is.
Hmm. Here's a patent from 2009 for a phosphor compound that emits light when excited by light. Perhaps we use a material in that vein to produce a 'CRT' like device that's excited by lasers. The lasers would go where the electron guns would be in a normal CRT, and the phosphors would be painted on the front as usual. The whole thing wouldn't have to be as heavy (or in fact made of glass) because you could probably get away without actually having it be a vacuum - instead, fill it with nice, dry nitrogen or something (to make sure you've got no dust in the works).
It's a thought anyway.
What type of tubes work with these? I assume a CR23 pin out?

There is equipment that allows the restoration of both the phosphor surface of a picture tube and the guns themselves. Essentially, they cut the neck off of the tube, scrape out the old phosphor, add new, repair the guns, re-vacuum and re-seal the tube.
I've read that they no longer do this (or are no longer in business?), but http://www.hawkeyepicturetube.com/ was one of the companies doing this service.
From what I've read, it is not even close to cost-effective.
I did read that the equipment for doing this type of service was available/abandoned at one point, and a retro Television organization (the Early Television Foundation and Museum) had acquired the equipment. Not sure if they are planning on doing the restoration service, or if it's compatible with monitors like our arcade ones.

There's an old time mom & pop elecrtonic shop in town....they have one of those tube rebuilding set ups........except their oven is about 20 X the size of the one in those posted video. I don't think he's fired it up in 5 plus years. Their building would be 150 degrees when he had tubes cooking!

Why not cut out the middleman and use visible light lasers on a projection screen?
Hey wait a second... I've got an idea. Now I just need to save up enough for a blue laser diode and optics...
Right now the amount of time/money you'll spend trying to get a new CRT monitor manufactured is WAY more than what you'll spend in trying to find NOS or burn-free old stock. Likely it will remain that way for longer than I'M in the hobby anyway.
That said, I have hoarded a few goodies myself.
