Hi Vince,

To protect the NST from the coil's RF, the following has become popular:

For general AC line filtering, the many common AC filters can be used.

I like these Corcoms from DigiKey but they cost like $27 each!  You can find
similar filters surplus and such for 1/10 that...

Radio Shack and many places sell MOVs (Metal Oxide Varistors) that clamp
excessive voltages on AC lines.  These are very useful if the RF high voltage
"gets loose" :-))

Cheers,

        Terry
