Final Version HV Tester

This is the final version of my HV tester. It supplies an adjustable voltage of 0 to 12 kV (or more) high voltage at very low current. It operates from a standard 12Vdc positive 2.1mm center pin wall wart supply.
It has a built in voltmeter, bleeder resistor system, and bright red LED current indicator.
I use things like this for checking coaxial connector installations for stray stands that often will cause future issues, HV low capacitance capacitors such as ceramic, air, or vacuum variables, and for testing tubes for gas or voltage breakdown.

You reinvented the Megger, very good.

Nice work. Awesome

Expected more of a drop on higher bands, great tuning for two 572's. Tuning Pulser, I want one.

Very nice and compact tester. Sounded like a rattle snake when it started to corona that coax.
Great job, great video! Are you going to make this a kit perhaps?

Is the schematic available?

Are you going to offer this little Gizmo for sale or release the schematic and plans?
