Re: "Beck unit which evolved from the Clark zapper"
Hello Paul,
I find your comment above somewhat distressing. The only thing that the Beck and Clark units have in common is the name "zapper" and that's where it ends. Thier heritage is entirely different and they operate on entirely different principles.
The clark unit was developed on the principle of frequency application resulting from direct experimental observations. The Beck unit was developed on the basis of electric microcurrents as a result of obtaining original research patent documents.
Dr. Beck's "hobby" was building and testing alternative medical devices. Failing to distinguish the two is to do Dr. Beck a disservice since he stated that the Clark device does not work. This is not a personal critisism since I have no experience with the Clark unit. I am merely quoting Dr. Beck who's devices I have used to great effect. In interpreting his statement from the context of his writings and lectures, I would take this to mean that it is not consistently reliable.
I have no knowledge of the Godzilla Unit but I assume that it uses similar (Beck)circuitry. I have a sota unit which I will base the following comments on. This unit can deliver quite a bite if you tweak the overly sensetive dial a little too far. Also you have to tweak the sensetive dial to nearly the end of it's travel before it "kicks" in!
Perhaps it incorporates a logarithmic pot whereas I think a linear pot would allow much smoother adjustment. Assuming that it also incorporates a 500k pot, seems that a lesser value would be adequate and perhaps even desirable. You could possibly even incorporate a mini variable resistor in parallel to the main pot to facilitate fine adjustment for even smoother results.
By using a fixed value resistor, you cannot adjust your unit to suit your individual comfort zone.
Hopefully this may prove to be of some help to you.
Neo.
