Yep, those are the ones I thought they were, and as I thought I
remembered,
they are too rich for me.

He also has the luxury of doing this for a living - I do not.

I can make them from any machinable plastic, banana jack parts, and a
modified PL-259 connector.  A friend of mine came up with a pretty
good design for his CO2 laser power supply (which runs upward of 20kVAC)

I guess I will have to scrap the coax idea, unless I strip the shield
off, but the shield was half of the reason for using it - I wanted to
protect against secondary strikes to the HV lines from the NST filter
- "defense in depth"!
