[Amps] To rewind or not? (3KA resonant filter choke)

[Carl]

I wouldnt ever run 5-6KV thru a 260.

Just about all VTVM's have optional HV probes and those meters will show you 
things a DVM will never do, even a Heathkit.

I use a Hickok 209A with that huge meter, a Fluke DVM with 6 and 20KV probes 
and several scopes for PS work and all have their strengths and weaknesses 
but internal breakdown is not one of them.
