[Amps] Hipot tester Info Needed

[Will Matney]

Harry,

I have one of those but not sure about the model. If I can dig it out, I'll see if I can find a manual for it. For checking tubes, a leakage of around 1uA is undesirable. Also check the HV leads on the hipot for cracking, especially where it goes into the hipot. The wires insulation gets old and brittle. I changed it on mine using HV lead wire like used for the CRT anodes on TV sets. It will carry 40 kV.

Best,

Will
