PET mono screens

Hi folks,

ROM problems aside does anyone know of a way I can test the actual CRT?
Last night I borrowed the screen from another PET just to see if I get a
garbage pattern from the board I'm repairing, but this one stays similarly
dark so I need to sanity check both of them.

Back when I was fixing my broken TRS80s I could use the CRT from a B&W TV,
is there anything oddball about the PET CRT that would stop me going the
other way and putting the tube in one of my spare TVs?
