@North there's some discussions of the challenges at groups.io/g/TekScopes/topic/co. the seal between the coke bottle (soda glass?) and the borosilicate tube with the electron gun is...tricky.

@tubetime oh, yeah, if you don't build your own electron gun. Just make it out of soda lime glass with dumet seals. I think I'll try to do a working CRT out of Boro first before I face the challenge of working soft glass, though.

@North yeah if you're not building the electron gun it would be easiest to sacrifice one from a working tube i think
