D75. Leakage across the high voltage terminals of the EHT transformer.
MotorBikeLes is quite right. There was some discussion about this fault in 2013 and also a bit earlier.
I posted the cure I have used since several times in April 2013 is to use a standoff insulator or a TV tuner ceramic feed through capacitor to make a new well insulated terminal. Reduces the risk of the wire breaking off as you try to re-insulate the paxolin panel. Search under Telequipment D83 EHT.
If you want to do it the hard way, a blob of Araldite will insulate quite well or I have also used Tensol 70, the perspex cement, even better.
You will soon be wanting to measure the high voltages. This keeps coming up. See postings of November 2011 (under D83) and more recently of October 2013 upon making a high voltage probe for EHT supplies, and is simple provided you re-calibrate each time.
