Would carefully unsolder the HV winding by heating the joint and unwrapping the wire from the terminal. Try not to flex the  wires as the insulation is fragile. Measuring the resistance from chassis gnd to each of the two affected wires. Should see on one about 392 ohms and 402 on the other. If you come close then I would proceed by keeping the wires apart and away from the chassis. Power up for 5-10 min and if the transformer doesn't get hot, belch smoke or fire your good to go on and replace the socket. Would add a layer or two of shrink tubing over the exsisting wires to provide so insulation. If you need a socket drop me a pm and I'll put one in the mail to you.
 If there is a much higher resistance then you are looking replacing the power transformer which is not too much of a big deal but can be costly of you go w/ a new one.
