transformer help needed

[Conard Murray]

Hi Guys,
A student at the university has approached me for help and I need some input
here. He needs an audio transformer with a 3K ohm primary that can handle
500 volts at 300 mA  and a 8 ohm secondary. This is part of a plasma lab
demonstration wnere they use audio to modulate a gas flame.
Any ideas out there?
Thanks,
Conard WS4S
