Have a look at this link to Alan Lord web site at Dundee College
http://old.dundeecollege.ac.uk/Sections/...igvolt.htm
It is the design of a high voltage insulation tester, which he used to remove the conductive coating inside a leaky UL41 valve.
I have tried this method and can confirm that it does work, although I used a more lethal mains EHT transformer powered by a variac.
