This CRT is dead, right?

I got this Mac SE cheap as "does not power on". I tested all the other parts from the machine individually and they all work, which is great; I was expecting a battery bomb or a dead PS/AB. After doing that, I noticed the tip missing from the end of the CRT. This will have broken the vacuum, right? I haven't tried powering this CRT on because I don't trust it...

Thanks everyone. I never got to (had to?) listen to the hiss of air into this one because it was this way when I got it. I installed a good CRT and the machine is working great now, though! I'd still say I got a good deal.

At least it's working!

My SE30 came this way but I didn't realize it until I powered-up after re-capping and was greeted by arcing inside the tube and some very alarming buzzing sounds!
I replaced the CRT and the dead driver transistor on the neck board, and all's happy now.

yup. I broke the CRT of a Macintosh Classic once. Once I heard the hiss of air entering the CRT, I knew it was cooked
Done, twice: once while trying to remove a stuck-in SCSI ribbon cable in a Classic; once when trying to remove a stuck-in CRT anode whatchamathingy.
One of the rollercoaster moments they don't tell you about when you enter the hobby.
