Dr Clark's Syncrometer
You will find this schematic in the book :  “Syncrometer
Science Laboratory Manual” , Dr Clark, Ph.D., N.D., page 4. 

All building details are in this book, and in “The Cure for all
Diseases” CFAD, Dr Clark.

At least in Canada, Radio Shack had changed its name for
"The Source". Many, if not all references given in these books
are not valid any more

Here is a general description of each piece, hopping this will

=    Speaker (2 inches = 5cm) Can be replaced by a small
sound/music amplifier and its speaker, for a better sound
=    Miniature Speaker Transformer is a 75mW audio
transformer,  8/900ohms Center Tap, 
=     The  “probe” can be made out of a banana plug, audio
plug or any rounded tip to avoid hurting the skin.
=     The “Handhold” is a copper pipe similar to those used
on zappers  (1/2 to 3/4" Dia (12 à 19mm) and 4 to 5" long
(10 to 12cm)
=     Plates are made out of 3.5x 3.5" (9x9cm) aluminum.
=      Transistor 2N2907 can be any general purpose
transistor as 2N3906 or 2N4403 (PNP).

Be aware : Syncrometer is not easy to master.  Dr. Clark
recommends 6 months of practice, 1 to 2 hours per day,
before testing for others.
I have tried, and make the choice to invest my time (for now)
on the zapper.

Commercial syncrometers sales for around $300US.  They
are not easier to use.

Certain Internet sites associate zapper and serious illness.
It is not our role to make such assertions. 

Illness does not interest us.

We leave it to the experts of the unhealthy states.
We are only interested to feel better, which is highly subjective, and to get rid of as much “invaders” who drain our resources, as possible.

These invaders, who live at our expense, we name them under the generic name of “parasites”.

We experience the influence of the zapper effect
on these parasites, on a hypothetical and empirical basis, which have nothing to do with medical or scientific rules.
