    Looking for high voltage silicone (or dialectric silicone),
    as it's also called, or a PTV anode kit! I'm in eastern Canada! Using it to
    repair second anode on rear projection T.V.'s! Global in Mississauga, don't
    even
    know what it is, & Mat haven't got it! Rono.

    Hi Rono...

    Suspect that you might have better luck searching for what
    us old guys used to call it in the olden days... high voltage
    putty :)

    Good luck, and take care.

    The grease that doesn't harden? Go to any autoparts store, they have it near
    the spark plug wires and stuff.

    I've used regular GE silicone II for this a number of times with no
    failures. If it has arced through the rubber cup I assume you're
    replacing it and not trying to patch it.

    Global does have it under an RCA part number but the cost is stupid
    Use GE Silicone...
    If you need the RCA number let me know .

    Oh man you are not going to plaster it all around the EHT cable

    Why why why why?

    Clean up the area with some light oil based fluid, if you do a good job, you
    will not have any more trouble,

    I used to do with color TV that worked OK mean while ##### ##### ######
    ##### from other techs that used to cover the area in silicone crap and then
    with time all the dust would get in it ARGHHHHHHHHHHHHH THE PAIN OF IT ALL

    Thomson, Philips, and Toshiba all sell the HV rated RTV for use on PTV
    tube anodes. It is not inexpensive, but is required per the
    manufacture due to the close proximity of the other wires and grounds.

    The key is to have a very clean tube surface and new anode that is also
    clean and dry. The rtv must be allowed to fully CURE before applying
    high voltage. To guarantee a full cure, I would wait 2 or more days.
    It is also important not to over-apply the rtv. Just enough to provide
    a good air-tight seal around the outer 1/4" to 1/2" of the hv anode is
    all that is required.

    Failure to properly seal the anode to the tube will result in hv arcing
    and premature failure of the repair.

    Regular acetic acid based silicone rtv should NEVER be used. The acid
    eats away the metal in the hv anode connections. The silicone is not
    guaranteed insulative at the votlages being applied.

    looks like a cases of;
