Is there a cheaper protection circuit I can use? Minus the capacitors I dont
even have 60 bucks into this.

Also, can you hook NSTs in series for more voltage? or just parallel for
more amperage? will a 7500V / 30mA transformer work decently until I can get
another bigger one? My coil is 30.5" / 6.25" and a 15 turn 6ga copper
primary.

Also does anyone have any info on Microwave transformers? Those look like a
good cheap alternative, are they reliable?
