I've been thinking about some of my machines that have built in CRTs.
I'm wondering how best to maximize the lifetime of the CRTs and the
eventual scarcity of replacements. Does a CRT live longest if it is
used often, or if it is left unused, or somewhere in between?
For most of these machines, it would be possible to route the video
signal to an external monitor and disconnect the power from the CRT
itself. The question is would that prolong the life of the CRT?
