RE: Power factor correction

My suggestion was 10KV 30 mA was 300 Watts not 3000 Watts.

You are talking about 900 watts, not 9,000 watts with 15KV 60MA as 
mentioned by another reply.  The emailer that I replied to seems to 
be talking about a transformer that are many times the voltage that 
Tesla coils and Jacob's ladders would tend to use  You don't do 
Jacob's ladders with X-Ray transformers DO YOU?  Am I missing 
something?  Can we get a confirmation of this from either Dr. R., or Chip?

I would certainly love to see a large Jacob's Ladder.  I would guess 
that bigger only sounds larger.

Sounds good to me.
