[Amps] SHV connectors...

[Carl]

With a quality mil spec RG-58A there should be no problem as Ive hipotted to 
5000V and have to agree with Jim.
RG-58A has a stranded center conductor and is very flexible and Ive used for 
almost 25 years at 3500V. Maybe I should replace it to be safe with a new 
length.
