Hi Wings

So let me get this correct. Are you saying that if I replace my inductor with a transformer and use a small dc voltage with a potentiometer on the the open windings of the transformer I will be able to tune the capacitance to optimize the circuit?
I was just trying the simple circuit they had posted because I thought it would be doable with what I had on hand. Tuning was tedious but I think the circuit shows promise in a looped system.

Hi Vince and Wings,

In the block diagram the upper left transformer is a step down type (понижающий трансформатор), I managed to figure it out from the text written above that transformer...   Hence it is supposed to feed (with a low impedance output, i.e. small voltage-high current) the tank circuit made from capacitor C and the primary coil of the right hand side power transformer.

Then here is a google translation on the block diagram Vince tried to test in his post #173:

**** start  (from link http://nshb.at.ua/load/svobodnaja_ehnergija/rezonansnyj_usilitel_moshhnosti_stepanova/21-1-0-589 )

The simplest resonance amplifier consists of only four elements.

Appointment of elements is the same as in the previously discussed amplifier. The only difference is that in the simplest resonant amplifier manual adjustment is made in response to a specific load .

Calculate the simplest amplifier can be simplified to the following algorithm:

1. Enable the power transformer to the network and measure at a given load current consumed them .

2 . Measure the resistance of the primary winding of the power transformer .

3 . Calculate the impedance of the transformer under load.

4 . Calculate the inductive reactance of the transformer under load.

5 . Select the value of the inductive reactance of the controlled magnetic
the reactor equal to about 20 % of the inductive reactance of the power transformer .

6. Manufacture adjustable magnetic reactor tapped starting from the middle to the end of the winding ( the more bends to be made , the better the adjustment in resonance).

7. On the condition that the inductive and capacitive reactance at resonance, calculate the value of the container , which must be connected in series with the transformer and adjustable magnetic reactor for a series resonant circuit.

8. Of the resonance conditions , multiply the measured current consumption loaded transformer to the amount of active resistance of the primary winding and the reactor and get an approximate value of voltage is needed to apply for a serial loop .

9. Mark transformer for output found according to claim 8 voltage and the measured current consumption of claim 1 ( the period setting of the amplifier is the most convenient to use LATR ) .

10 . Powered from the mains through a transformer of claim 9 input resonant circuit - ( series-connected capacitor loaded primary winding power transformers and reactors ) .

11. Changing the inductance of the reactor by switching taps configure the primary circuit in resonance when the input voltage ( for fine-tuning can be slightly change the capacitance of the capacitor connected in parallel with the main capacitors of small capacity ) .

12. By changing the input voltage to set the voltage on the primary winding of the power transformer 220 V.

13. Turn off and turn LATR stationary step-down transformer with the same strain .

Widespread use of tuned amplifiers power frequency can significantly reduce the load on the distribution networks and reduce capital costs for the introduction of new electrical capacity.

Scope of resonant power amplifiers power frequency - stationary and marine electrical systems . Mobile objects appropriate to apply transgeneratory at higher frequencies , followed by converting AC to DC .
**** end

I think iT would be better to use a power transformer with a 230V or even a 380V primary coil, preferably with very low DC resistance winding so that the tank circuit should have as high Quality factor at 50 or 60 Hz resonating with capacitor C as possible.

Yes, basically you get a tunable coil with the DC current biasing the core of that coil, this is what is shown in the block digram with the feedback circuit:  some part of the output voltage is rectified and fed back to two variable inductors, the control coils of which are cross fed by this control current to cancel 'unwanted modulation' for the tank circuit. With this feedback circuit the effect of the changing load conditions is compensated for within a certain load range, this is why a constant load is mentioned for the simplified block diagram where there is no feedback.  At least this is what is suggested in the Russian text.

you tune the circuit by Variable inductance instead by Step by step capacitance.
