i wonder how hard it would be to make new CRTs today
what part of them is it that's illegal now? Is it the leaded glass? Or something with the phosphors? I don't know how you could get around the leaded glass unless a CRT that blasts the viewer with x-rays is acceptable (it is in xray machines but not for screens), but if it's the phosphors you might be able to develop other formulations that work

@Felthry I'm not aware of any legal problems in making CRTs, just market-demand problems.
At a guess there's probably still some manufacturer for airline and power plant equipment making tube TVs, since it's hard and expensive getting replacement equipment developed and certified for control surfaces.
@Austin_Dern i'm pretty sure there are regulatory restrictions stopping them from being made? on top of the obvious lack of a big enough market. i'm not sure where we learned that though

@Austin_Dern that more emissive coating *could* be something toxic (i think thorium was common at one point for certain gas-filled tubes) but there are nontoxic things that work too
