500 VDC Capacitor Leakage Tester

This is a demonstration of my homebrew high voltage capacitor leakage tester for testing old coupling capacitors in vacuum tube equipment.

This is a quick-and-dirty video shot with my smartphone. I originally put it on YouTube just to make it easier to show to friends and family. But it seems to be gaining some wider interest.

If you'd like to see a more comprehensive video that discusses my design ideas/process, and includes a schematic and internal views of the device, please me leave a comment and let me know. Maybe I'll make such a video if there is sufficient interest.
