We had one in an auditorium where I work. Only problem is it was underneath an MRI scanner. Every time they’d open the door to the MRI, the magnetic field would knock the projector tubes out of alignment.
The technician who came out to work on it said it was hopeless. He told us he had a customer whose projector would get out of alignment if he moved a speaker in the room.
I was so happy when we finally replaced it with an LCD projector.

The safety warning about CRTs is no joke. My dad used to work appliance repair in the 80s. These guys were all well trained in that shop. They had a shelf of tvs with dates on them. No tv was to even be looked at until at least 3 days from dropoff, then they discharged the capacitors. They hated the tvs most, because they ran test after test before plugging them back in. I miss the free crap Dad would drag in due to missed payments or abandoned electronics. We had a 24 in industrial microwave that I miss to this day. I could be lazy and microwave anything in that damn thing, regardless of metal content, and could defrost a small turkey.

What do you mean about the metal content in the microwave? Does the larger chamber make it somehow immune to arcing?

Metal is only a problem if it gets near the sides/top/bottom. There are even microwaves that come with a metal rack for the middle that’s suspended by plastic tabs.
Bigger size makes it easier to stay away from the sides.

I was a kid, so don’t remember everything as my Dad explained it, but it used a more powerful magnetron with a pulse system and used a fan to blow the heat. It also cooked hot pockets without leaving the outside cold and lava inside. Moreso than that, I don’t remember as it was a tech geek dad talking to a 12yr old teenager that only cared to listen to the first half. I was a shit, and I regret ignoring the trove of knowledge that man had.

Probably a “strong enough to still heat stuff in a metal bowl” thing.
