[Amps] HV checking

[David C. Hallam]

Get a good HV probe and be careful.  As long as you are a little nervous
about doing the testing you are probably OK.  It's when you don't give it a
second thought that you're in trouble.

I make sure the workshop door is shut and locked and double check for dogs
and cats under the work bench before I start.

Hi John,

When it comes to testing HV circuits, there is only one safe approach.
Volunteer to teach ham radio to a local elementary school.  Once you have a
few budding ham candidates, pick the most irritating one for the job.  Since
most of these kids only weigh 60 or 70 pounds, you can easily suspend them
above the amplifier power supply in question with surgical rubber tubing
attached to eye-bolts in the ceiling over your work bench.  Have the kid
hold the probes across the supply's output and hit the switch.

Fluke makes some excellent HV probes.  They have a 6 KV and a 30 KV model.
I own, use and love the 30 KV one.
