Re: "Beck unit which evolved from the Clark zapper"
Paul, I couldnt possibly put it any better than Neo has-very acurate.
Both blood electrification units have evolved from dr. kaali
s, et al research/patents in 1990 at the albert einstein college in new york and their incredible findings with devitalizing...I believe it was the hiv virus. Both bob luhrs and bob beck have made their own designs based on kaali's work. No reason to work around patents cuz beck found many many patents on similiar blood electification dating back 100 years (approx).
V's 6 speed godzilla unit is able to adjust the current down to .5 milliamps if not slightly lower. If really electrosensitive, he could make it even lower. Address all questions to V, and he will help you make the modifications on your current manual unit. Neo may have some info too, but alas I am the electronics village idiot so must defer to them.
Clark was inspired by rife.
Beck and bob luhrs and V by the kaali experiments in 1990.
