NSTs are fragile.  The ARSG probably overvolted it and
killed it.  I doubt an RF low pass filter would have
helped any.  Best thing to do with your new 15/30 is
to run a static spark gap.  Keep the gap spacing
conservative, and use a larger-than-resonant tank cap.
 These measures will help your NST live longer.

Cheers,

Greg
