Yes, it is also hard to analyze, because that Mazzilli circuit is really a Load Controlled Oscillator (LCO). 
O course, the capacitor connected across the primary winding is also a major frequency-determining component, but it's reasonable constant.

It would be much easier to analyze the entire system if the oscillator driving the primary winding did not change its frequency, regardless what happens in the transformer.
As it is now, it is very difficult to separate the effects taking place in the transformer from the effects in the oscillator, because they influence each other mutually.

Anyway, it is unusual that adding  load decreases the oscillator's frequency.

Dear Verpies.

Do you think that as a greater load is presented the input volts drop thus lowering the frequency??

Perhaps a ZVS type of oscillator like MenofFather's could be tuned in to the cores frequency??

Just some ideas. But now after my latest tests it is definitely the core that plays a vital role with this device.

Cheers Grum.

Input 13 V 3 A. In pipe ferite cores. Output 60 W 220 volts lamp. It brightnes about 150 V. On NE555. Duty cycle 50 %. Parallel primary 0.33 uF capasitor. Primary white two in paralel 2.5 mm2 wires (5 meters). Secondary tin emalated wire. Transistor 60 V 50 amperes RFP50N06.

4.5 A. 10.5 V. Same all, only lamp now 150 W 220 V. It brighness about 80 maybe volts.

Here is the latest from the split core saga!!

Before Morpheus gets you, please let me know what is the inner circumference and the outer circumference of your ferrite core when the two halves are tightly pressed together.
I need this to estimate how long it takes for the acoustic wave to travel around the circumference of the core.  This might explain the kHz frequency.

Yes, I saw the phase offset between the input and the output.  Am I correct in assuming that this was done with two piezos (one in each gap) ?
Anyway, I'd like to know the exact magnitude of this offset (in nanoseconds) for my speed of sound calculations. 
The scope was too far away for me to see the setting of the horizontal timebase and the magnitude of the phase offset.

Also, I'd like to know how the core gap influences the inductance of the largest winding and the frequencies at which the acoustic peak amplitudes happen.
"How" means that I'd like to see a table of inductances and frequencies (listing of core gap measurements in mm is optional). 
This data will allow me to analyze the important relationships of key effects in the core, such as magnetic flux density vs. the acoustic resonance frequency.


P.S.
What are the specs of that 40W amplifier?
Please put some cheap narrow ceramic disk magnets in the gaps between core halves and repeat the measurements.
Please don't use NdFeB, SmCo or AlNiCo magnets because they are electrically conductive and this allows eddy currents to develop - we don't need yet another variable to account for.

The voltage drop is possible, but not much with a stiff battery.
Certainly the same effect (low impedance of the load reflected back from the secondary into the primary) would decrease the apparent inductance of the primary and outweigh the frequency decrease caused by the voltage drop.
Good thinking, anyway
