What is this?

I have not tried tapping the screen to see if they move, I'm hesitant because of implosion risks.

Here's a question: could this be a total loss of focus? I don't really trust the focus rect in this set, and I have a spare I could try. My guess is that the screen would just be really fuzzy if that happened, and I wouldn't see much of anything at all. Just a blur.

Sad to say, but everything that I have read here seems to be consistent with the shadow mask being totally out of position, not just bent or dimpled. Focus appears to be fine.

Does the box show any sign of damage? it would take a fairly severe bump to dislodge the shadow mask spring clips from the posts on the inside of the front panel. Anybody know how many clips are used in this roundie? ...3?

I suspect that the tube was fine when Scotty shipped it... I would guess that he tested red, blue and green fields to evaluate rebuild quality, and perhaps eliminate any screen contamination that might have occured during the rebuild process.

TubeTypes' test may well reveal a loose shadow mask assembly, but it is also possible that the mask could be wedged in its' present position... for sure worth a try!
