Hi Jim/everyone,
I am perferably looking for plans to build a
transformer with an imput of 120v 5-20Amp and an
output of around 15kv and at least 500mA. Sorry for
the confusion ;-)

Sorry Bobby,
What you are asking for is physically impossible. You can't output more power than you input. You see, since P = E x I, 20 A at 120 V is only 2400 Watts. Therefore at 15 KV out, you can only get 160 mA. An output of 500 mA @ 15 KV is 7500 Watts, meaning the primary has to draw at least 62.5 Amps.

Hope this helps,
Matt D.
