Wouldn't that be Quad-clops?

And the point of this is...?

Maybe the extra CRT is IR, allowing for use with NVG for combat simulators.

Nah, its just a way to test extra tube lying around with out needing a test chassis with one CRT bay open. you make an extension cable for the umbilical cord and use a block of wood to keep the tube level, then you use the greens g2,a nd video cable for testing along with its HV socket in the Splitter.

I did the same thing when testing the Thomas tube mods to the VNB's.

I've seen some with 4 or even 6 tubes to increase light output:

(1) Two green tubes for even more light output:

(2) A stack in one case! Same as just stacking two 'regular' projectors (twice the light output):

Two greens? I would think you'd run out of oomph in the blue long before you could take advantage of an extra green...

Maxivideo mid eighties. Riemert Sony Stack for 'Studio use'.

Of course a second green overlay off-set by a quarter pixel in two directions would make for a little four channel 4K luminance beamer, a la the JVC 8K demonstrator in the NHK Super Hi-Vision development project.

I like the first one with four tubes, but as Gary alluded to I would put another blue in it.

Cyclops doesn't look to hard to do and another blue could help with light output.

2 greens are useful for stereoscopic projection where you use fast phosphor green tubes that have significantly lower light output than standard phosphor green. By using 2 green fast phosphor tubes you effectively compensate for that decrease in light output.
