I regret taking all my old tube monitors to Goodwill back in the mid-2000s. I saved a Commodore 1942, at least, but I sent all the rest away to die.
I appreciate the CRT modeling in emulators, but a hardware device that passes thru a display signal and provided sub-frame CRT artifacting and phosphor modeling (particularly if it supported 240P) would be bitchin'.
FPGA based devices that can do this, and quite well, do exist, they're just expensive. The RetroTINK-4k Pro is the top of the line as of this writing but it's a $750 converter.
