M.Zap4R from Maestro-Zapper

The M.Zap4R made by Maestro-Zapper (Fig_1) is delivered with copper tubes, almost ready to use (it is
send without a 9V battery). Copper tubes are of good size (comfortable to use).
A manual in PDF format with 41 pages, describes this model , and the M.Zap3a
The graphics on the front face are nice and functional : at glance, they give you key information, related to
this unit.
The battery compartment is easily accessible.
The use of output banana connectors makes the unit compact, and if necessary, easy to repair the cables.

Mechanical:
Case size: 2.6"x3.7" x 1.1" (66mm x 95mm x 29mm)
Total length of tubes and cables : 42 "
Type of electrodes: Pure copper (99.5%) tubes 7 / 8 "Dia, 4.5" Long.
PCB assembly : conventional and SMD components.
Comments: Circuit held in place by 2 screws at the rear, and by front panel.

Electrical Characteristics:
Battery: 9V SHD, Alkaline or rechargeable
Protected against reversal connection of battery
Test Voltage: 8V to the input, converted to 10.87V (measured) for the 7555
Average current without load: Nominal: 2mA - Measured: 1.74mA
Average current with load (Dummy Load) : Nominal 4.5A 5mA.
    Measured at 30kHz: 6.20mA
Comments : The booster regulator supplies the output stage and maintains the 11V voltage down to 5.5V
input. This circuit is rare on zappers of this kind.
Electronic Features:
Oscillator 7555 (CMOS version of 555)
Freq_1: Nominal: 29.09kHz. Measured: 29.21kHz (0.4%) 55% duty cycle
Freq_2: Nominal: 2.5625kHz. Measured 2,559 (0.2%) 50% duty cycle
Rise time: 118nS without Load, 71nS under Load.   Around 3.5MHz cutoff frequency at-3dB

Comments:
This zapper is described as having an adjustment of frequency. On this device:
Freq_1 goes from 77.76kHz max, to min 5.95kHz
Freq_2 goes from 781Hz to 7.27kHz max (with Freq_1 adjusted to 30kHz)
The adjustment of Freq_1 affects Freq_2 but Freq_2 does not influence Freq_1
Adjust Freq_1 first, then Freq_2
= Led decreasing in intensity with the wearing of the battery. Led extinguish around 6.5V of battery.  The
booster still maintains the output voltage to 10.8V at this low voltage
= LED lit when the output circuit delivers a current (The zapper is well connected)
This function is very rare on this kind of zapper.
This zapper has only an internal resistance of 1k_Ohm (no "Super Stable Wave Form” circuitry)

A lot of harmonics, but with around 100 less
energy

Overall : This zapper is an
improved version of the basic
zapper of H. Clark for 4 points:
1_ Uses a CMOS version of the
555, consuming much less power,
which leads to more sessions with
the same battery. Alkaline
battery not needed. SHD is
sufficient (and less expensive).

2_ The use of an 11V booster-
regulator allows all day long
sessions for uses requiring a
minimum voltage of 9V by the end
of the session, as plate zapping
or Homeography and removes any
concern about the weariness of
the battery

3_ The frequency adjustment
allows an accuracy close to the
maximum allowed by the 7555
(about 1%). Interesting if you
want to experiment with zapping
frequencies, or adjusts to other
values.
As delivered, the 30kHz allows a
basic zapping with a good
transfer of electrical charges, and
allows Freq_2 to zap using
frequency harmonics, being
adjustable on several Rife’s
frequencies, and 1kHz, 2kHz,
2.5kHz, ...
Warning: The use of a frequency
meter or oscilloscope is required
to re-adjust the frequency.

4_ Output current indicator
(zapper is well connected) is a
rare feature, and very useful.

= Workmanship. This zapper is
well made to last a looong time.

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.
