Beefy HV power supplies like this, at high potential, split into 3 tubes to make as bright a raster as possible (you need sunglasses to look into the raster when adjusting). The beam in a PJ CRT has been known to crack the tube if deflection fails from the hot spot, and the tubes are liquid cooled.

I don't believe the glass is leaded either, as you don't sit that close to the projector. Hence the decent amount of X radiation where the beam strikes the phosphor, but it drops off as per the inverse square rule so you have to be fairly close for problems (like someone working on the things all the time).
