Yet again I'm a nobody. Well, if I'm not in the
set of 'everyone' I must
be, right :-)
It's comme-il-faut on this list by now, what is one to do?

I've never heard a CRT squeal. I've heard one
hiss, but that was when the
pinch-off tube got cracked and the vacuum was leaking out. That effect
only lasts for a few seconds, and then the owner starts squealling as he
has to look for a replacement CRT.
The squeal from most monitors/TVs comes from the
(horizontal output transformer, line output transformer, call it what you
will). THe core vibrates at the horizontal scan frequency.
Is that the neck at the back of the tube? I see a key-like screw protruding at
a 90? angle from the neck, which seems to be coupled to a metal band wrapped
across the neck.
The cure is to make sure the core can't vibrate. If
there are clamps on
the core, tighten them (not hard enough to crack the core of course. If
not, then often a squirt of hot-melt glue around the core and windings
will silence it, but don't blame me if it ruins the transformer.
There is a big squirt of glue around the mountain of wire (what you call a
coil, I think) where the neck begins.

Don't worry about that. THis effect has not other
than annoying sound)
That's a relief.
