Hi Aaron

I've been using a RC filter that I got off Greg Hunters site (Greg
Garage) for my 6/30 NST and have not had any trouble.  As this is my
first coil it would have had a bit of abuse (I didn't have an RF
connection accidently and it survived).  I've been getting 15" off my
3.5" 6/30 NST coil but I've eaten a few caps due to  a very much
underated MMC cap.

Cheers, Chris.

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?
