I do not understand why you insist in perpetuating false and misleading information. Zp does not follow Dr. Clark. They set their own path.
>- He thinks ... I think
The difference is that I have provided real data to back up my claims while all that I can see is that you have twisted and misrepresented a lot of what has been shown to be otherwise than what you claim.
Dr. Clark uses a 555 timer in every book that she has published and has not endorsed the CD4069 which BTW, ZP is the only zapper made that uses this substandard chip!
