They've had the cure for tube burn since 1939 and never told us.
I bet they have a cure for the common cold too..  Bastards............

Well I can see one issue there for sure. The gun is offset to the left. How would any right winged guy ever be able to use one?

"ionization blemish" is different than tube burn...

| ieee.org wrote: | The form of the ion blemish is a function of the form of focusing and scanning used, being a small central spot with electric focus and magnetic scan, and being a circle about an inch in diameter with magnetic focus and scan. The blemish is due to chemical poisoning of fluorescence by negative ions formed on or near the cathode. The paths of such ions are substantially unaffected by the magnetic fields normally used with cathode-ray tubes. The path followed by an ion through an electric field is, however, the same as that of an electron starting from the same point of rest. Thus the ion blemish has the same shape as would the electron spot were the magnetic fields only removed from the crt. The use of a backing layer such as aluminum reduces the blemish but does not eliminate it, apparently owing to porosity of the backing layer. Such a layer has, however, other beneficial properties not related to the blemish problem. The ion blemish can be eliminated by the use of an ion trap, which is a device usually located in or near the gun.

I know. I just thought the ad was funny with the bent gun......

Everybody already knows the true solution to prevent tube burn......Proper setup and Lower brightness/contrast........

So is your projector really where you left it or is it just a wave of potentials when you're not looking at it ?
That would explain any convergence issues and also give you a damn good excuse ...

The most important question... In what state is Schrödinger's Projector?

This begs the question when you leave your house is everything in it actually there where you left it or is it just there when you look at it?

I guess until you look at it It could be just about anywhere.
Maybe that's why Curt ended up with so many projectors...
