I did some improvements to my CG-3000 ATU. All the caps in the output part of the PI network was changed to western branded 6kV low loss ceramics from Vishay etc. See pics.






I have been working on a new HI-POT tester ( high voltage tester) for checking breakdown voltage of vacuum tubes, RF vacuum capacitors, HV cables, RF relays etc.
