Re: Superiority of the magnifier

Hi, I personally think Maggies are great, but most likely you will not
"see" a great increas in V vs input power. Why do I like them so much?
Well the fact that you can physically move the tirtary some distance from
the pri/sec allows you to use physically smaller coils, and worries about
pri/sec srikes is no longer. I have used a driver tertary combo (six inch
driver and a four by eighteen inch tertary) from 200 watts to 1800 watts,
13 to 52 inch sparks, respectively. At 1800 watts I get diminishing
returns due to the small size (acually low inductance) of the pair.
