Tom: Rember the KISS princaple. The simple way to do it is to get a older
audio output transformer ( best with a 4 ohm and 16 0hm winding ) or you can
add feedback winding. with a 2N3055 transistor oscilator you should get
600v. you may nead a voltage doubler if not enough voltage is produced. A
two transistor Astable multivibrator circuit is a good choice.
