Re: Anyone have a neckboard or a connector for a 19VLUP22?

I have to disagree on that one.

The de-focusing effect is only supposed to occur _during the death star
explosion_.

In normal operation, both bright and dim vectors should be in focus.

I have to agree with Ian, sounds like a bad tube, or on the off chance, low
HV/Screen/Focus. What is the HV reading?

I'm curious to see if you can cure that with rejuvenation; let us know.

I don't have a CR-24, or I'd just lend it to you, but maybe someone else on
the list does.

Good luck.
