At your command!

Here's a couple shots of it running, this is with the NOS tube.
It doesn't seem to get all that bright, except when you adjust the controls it'll get brighter for a moment then settle back down, I think perhaps it needs a signal to work it's best.

All I know for sure is you have to be really careful where your wires are laying when you turn this thing on, anything that gets in range of the HV area will get zapped! I don't have the cage on it yet though, wonder how much X-rays it makes if any?

BTW, when it's installed and adjusted properly the screen won't be filled like it is now, it's supposed to be a bit smaller than the tube and keystoned slightly to compensate for the angle of projection, this can be seen on the face of the old tubes in the brown Phosphor.

A pair of magnets attached to the sides of the CRT do the keystoning.
