    The one in it is stuffed - no degauss.

    Has 3 legs



    All the other ones I have replaced have been 2 pin.

    So I cant find this part for sale anywhere that does one offs, is there
    an equivalent I can sub in that is easily obtained?

    The schematic I found makes it look like 2 PTCs internal to the one
    case, but I have no idea on the values of each of them.

    Also this TV seems to leave the PTC live all the time. Others I have
    used have had a triac to power it up only when needed. Perhaps thats why
    its a different one?

    3 legged ones are normal these days, one part is a heater Plus they are
    always on..

    Try Tradetech

    The resistance is important and does depend on the CRT size.

    So you will to get the correct one.

    Have the make, model number and version handy so they can cross
    reference if necessary.
