Wow, yes, preventing sputtering on the glass seems to be the answer -- remembered I actually have some worn tubes that have heavy silvering only on parts of glass where their anode meshes have small openings. Those anode meshes really look like they do prevent sputtered cathodes to go through them (or do they absorb the sputtering?)
(Now I'm curious whether my mesh-less tube actually goes dark and silver all over, but I don't dare to experiment it because I only have one...) Thanks for all the inputs! 2017年2月13日月曜日 7時13分10秒 UTC+9 MichaelS: > > Ah, yes.
