Calling on all you CRT experts. I caught this one looking through the CRT pics on Frapper and do not recall ever seeing a CRT like this before. What is it??


Thanks!

BarcoReality 912. 12" tubes, very rare.

Yup, 330 lbs of CRT goodness (actually, from what I recall reading here, the 912 is actually not even that great, compared with, say, a G90).

Can someone explain how this would not be the best CRT on the planet with 12" tubes? Not saying it is, just curious what is wrong with it. Looks like a beast

Almost looks like a tank turret without the canon.


I agree with Scott I would think this would have everything beat.

Moved to discontinued products on the Barco website less than a year ago. Don't think there was a split-pack version, unlike the 812.

Scott

Lenses are not the greatest.

No colorfiltering...

Bandwidth...

Phosphor still limited by bandwidth...


And so on...

I would like to see one after Mike Parker has had his fingers on it for a couple of months.

Those are some crappy looking lens though. It looks like someone took 9" lens barrell and fitted a larger optic on the end of it.

I don't know where you guys read that all the time.


It's the 812 that's seriously lacking.

Based on the original 8-series electronics. It's insanely bright, but resolution-wise isn't stellar. A well set up 1209s will most likely be better.


The 912 is much improved though. It's a Reality 909 on steroids.
