If anyone here needs to take out a big crt and wants to make it safe,
sideways tap along the plastic connector on the neck. It will break the seal
and you get a gentle inrush that takes some time. Sometimes it takes several
taps but it will unseal without breaking. ALSO DO NOT carry the anode side
against your lower abdomen or worse, your crotch. BIG ugly surprise when
several KV discharges against you when you. First the crotch fire and then
you drop the tube on your feet. Bad situation. Before you take the tube out
of the TV use a long screwdriver (insolated) and a jumper to ground and
discharge the thing.

I have a friend who removed a rather large picture tube from a console
once. I think it was around 27" diagonally. He wanted to dispose of
the tube and electronics and re-use the cabinet. The tube was much
heavier than I would have thought. I guess those tubes have to be
pretty thick on their face if they are to be anywhere near flat.
(And, the glass there is probably leaded to cut down on soft x-rays.)
Anyway, we pondered whether the picture tube would float or not. I
said it would; my friend said, no, too heavy. We were going to fill
a large trash container with water and test it, but never got around
to it.
So, what's the verdict: sink or float?
