Re: magnifier vs two coil system

John,
Why does Richard Hull's magnifier and some of the other designs that I've
read about use break rates of 1000bps or more? They seem to use smaller
capacitors and higher break rates. Also, I've seen the photos of small
helical resonators producing very large arcs. Richard seemed very excited
about this in his writings. Has this fallen out of favor and does he no
longer believe that this is the proper way to construct a coil?-----
