The extra current helps a bunch. Power is Volts times amps. Two 5kva 7000
volt transformers would work great. Use them is series and connnect the
center to ground just like the neon sign transformers. You could even use
the single bushing transformers which are usually earier to get and just tie
the cases together. You will need some inductive ballast and resistive
ballast in series with the primary to run them - and a big variac.
