Re: Safety Chokes

Original poster: "Dr. Resonance" <resonance@xxxxxxxxxx>

Sometimes safety chokes can produce unwanted resonances with a NST.  You are
better off using Terry Fritz's "Terry Filter" which incorporates varisters,
small caps, and a few 50 watt resistors for effective filtering.  It also
employs a safety gap off each xmfr bushing.

Perhaps Terry can post the reference to his archives for this filter.
