why the resistor in parallel with the transformer?
it only eats up power
First eat up some power and do tests on a smaller transformer before I connect the HV ESL transformer!

Update,
My audio amplifier is producing a sine-wave signal. I connected one 6.8Ohm/50W resistor per channel in series. I use one channel where I connected a diode in series with the resistor. Now I have halve wave rectification. See below.
I want to do full wave rectification so I made a diode bridge, but the signal is not what I had expected. Resistor was connected in series to the input of the diode bridge. It is still halve wave. Any ideas? Does the amplifier require/wants two resistors for pos and neg halves with diode bridge in between?
Problem is that the signal is below zero volts! Also when higher frequencies are used the signal gets distorted (type of diodes are BY254)
You can also see the AM modulated signal that is generated (just like in the patent) for input signal to the step-up transformer. (Unipolar pulse from a rectified sine-wave) Eventually the amplitude doesn't go to zero/below volts!

Yeah exactly , like I said  ...

Class b puhs pull aint good , that backspike spike right there could *  up everything .

Push pull is like this , transitor falls below .7v , reverse voltage . reaching negavte -0.7 , imedance rises 10000 fold , , OMG INDUCTIVE SPIKE ... It works for music but this is water science , your shit better be pure ... This is not like o it will probably make no difference , just make it pure and forget about it you know ...

Here is a common and easy way to run a transfo , class a . type single ended .

BUT single eneded needs a big *  transfo with gaps otherwise it gets aturated quick , dont expect to make a power type of these seriously , it will cost ur arm .

I am not using single ended but push pull type class a  , but both work well , difference is that single has a larger a larger more expensive transformer . The type you need to make yourself you know ... That esl transfo must have been ... rofl ...

Here is the simplicity of class A single ended .

Puharich probably used pure class b with tubes , however , such an ampifier is at best 78% efficient , you might get more like 72% in real life . So whatever gas he had it better have been good ... You need more than 120 % faraday here ... Amps were most likely very low if ceramic was there... but remember there is other losses other than simple volts by r , coupling , radiation . Its hard to say the true potential of Puharichs's technology .

class a has its problems with AM also , check out this example , basicly the lower power you go the more dc is flowing , it does follow a certain rectance tho since the enveloppe will be moving , but a low frequency am  will make alot of wasted current . dc is unaffected by the primaryes reactance . It just flows straight down V/ wire resistance + 1 ohm safety resistor ....

edit rofl , forgot to attack images

Update on my resonance WFC progress...

Made new coils as seen on the VIC box. One of the problems I have is the core! You can see I have not a UU/UI core.
Instead I want to measure what's happening with signals from the VIC coils with a I core.
The coils orientations on the core are very important.

Take a GOOD look at the circuit made by Stan (fig.7-8 690) I have never seen someone model this !!!

Do we have a clue how this circuit works as a model? If you do, you know we need a PLL to make it work...
This VIC is a dynamic system with feedback. Not simply a LC system with one fixed frequency!

To make it clearer:
- sec (Cd / L / Rp /Rs)
- prim (Cd / L / Rp /Rs)
- choke 1 (Cd / L / Rp /Rs)
- choke 2 (Cd / L / Rp /Rs)
- pickup (Cd / L / Rp /Rs)
- core
- cell C and R

There are a lot of parameters in this VIC system interacting on each other (not all parameters are shown here).
If someone can model and simulate "simple" magnetic coupled coils please try and model fig.7-8 690 and take a peak at the chokes what they do and how they interact on/with the wfc. Then look at the diode function on the chokes. What happens at sec. coil when unipolar pulses go into a prim coil in the VIC on resonance. "VIC resonance" is the key. Then look at the wfc C (amp restriction and voltage takes over).

Driver for a MOSFET from pulse output from a PLL or 555 timer circuit to pulse the VIC primary coil.
I wanted to feed about max. 1 amp into the primary L1 coil at 12V.

I have been experimenting with this for a few months and this is my VIC model for the resonance wfc.
(note. There are a lot of parameters in this model before you can build this. All parameters in the real VIC are not simulated in this model. This model is showing the simple version)

We can see the Charging Chokes 1 and 2 at work and the function of the Blocking Diode as Stan has written in the patent (remove the diode and see what is happening).

You should play with GATE frequency to see what happens with the charge in the cell also change the values in the chokes and the cell capacitance and resistance. Gate frequency is low (change it and see why)
The voltage can be 10kV when you change the input voltage from the Pulse to 200V (this is the stepup coil 24V to 200V) Stepup can also be simulated (voltage can go up, current is restricted, CHARGE IMPULSES)
Experiment with the gate to let the cell discharge to min. of 2kV (when correct values are found)

5kHz is what SM has written in his patent, why that is choosen has to do with the core material (iron) higher frequency has no purpose here (core saturation at max.10khz)

Note that capacitance and resistance of the cell is changing (not in this model) the resonance frequency so this has to be compensated by a PLL to run the SEC at resonance. A pickup coil is on the core between the PRIM en SEC.
The changing has to be compensated because the charge is altered in the cell (voltage has to be HV) this is done with the GATE frequency.
Magnetic coupling is not shown, all the coils are magnetically coupled (coil interactions). This changes also the resonance frequency of the SEC coil due the core magnetic fields.

This is as close I can go for a simple model at this time...

Feedback is welcome!
