Hi Kurt,
A good (or at least gas free) 4-1000A should exhibit less that a uA of
leakage up to 20KV.
Check it cold.
Also ensure that the glass is clean prior to the test.
73 & Good afternoon,

I have a 4-1000 tube of questionable origin. I don't have an amplifier to test
it and before asking someone to drop it in their amp I want to test as best I
can first. My Hi Pot setup goes to 10KV. What voltage should I be able to go
to (grid/anode)and what would be an acceptable leakage (in micro amps)at that
voltage? Should this test be with or without energized filaments? Anything
else I should do or know about. Thanks in advance, Kurt...
