Need an adhesive for a CRT coil

I have a CRT monitor that has a dodgy Vertical deflection coil - the
thin copper wire seems loose in places and far too often I can hear it
oscillating - it's a very high pitch annoying noise and i'd like to fix
it. My first thought is to smear some sort of adhesive or epoxy around
the coil to hold it in place, but im conscerned weather this might have
adverse effects which I may not be aware about.
Any crt experts out there have any recommendations on what kind of gluey
substance can be used? or perhaps there is a better method of dealing
with this sort of thing (which doesnt involve the skip)

thanks in advance,

Use Silicone sealant !

the Vertical Coil runs around 30 to 120 Cycles /second barely audible
the Horizontal Coil runs around 15000 cycles/ second .

The Squeal is usually generated by a mechanical problem with the Flyback
Transformer.

BEWARE that some silicones are conductive until fully cured ! That
'vinegar' smell is acid which is the conductor. Great stuff if given
the time to cure.

I think I have some of that hermetite stuff I used to use on the car
gaskets. red or blue?

blu is IIRC neutral cure (if the same as the blue permatex stuff)

hmm, vinegar.


so use blue.
