The general rule among people I know is LEAVE THE TUBE
ALONE. If you have
two units, one with a bad tube and one with bad electronics, move the
electronics, not the tube. etc etc. Handling a CRT is just too dangerous.
Generally wise advise, but probably because of the economies. Replacing a
tube (or any of the other high voltage stuff) can turn your wallet inside
out.
As far as actually handling a tube - no they really are not very
dangerous. If one makes sure to drain any high voltage points (twice for
each, at least), follow all of the other high voltage advice already given
(and probably in the FAQ), and do not drop the tube, you will be fine.
Post 1960 CRTs are actually quite tough and will sustain a great deal of
physical abuse. When they break, the neck shatters first and lets all the
air in. The days of the nasty implosions due to no safety glass are gone.
