Don't anymore, but I use to fix bad NST I came across. After the top of the
NST was off, I would place it on a wire screen that was supported above the
bottom of a large pail. Then the pail would be filled with diesel fuel up to
the level of the screen. I would rig up a recycling system that would
continuously pore the diesel fuel over the tar. The system would only be
operated when I was present for reason of safety. It would take three
evening to clear out the tar. The process could be helped along by picking
out chunks of tar that became loose. In this way I could avoid damage to the
transformer. The problems with the HV windings were usually in the top few
layers. After winding off a few layers, the problems would be history. Sound
simple, but the wire is very thin and it often breaks, especially at the
edges of the coil. If this happens, I used a needle, magnifying glass, and
an ohm meter to find the lost wire end. Sometimes the wire would not wind
off because of epoxy. Heating with a heat gun will soften the epoxy so that
the wire can be pulled loose. The process requires extreme patience.
