Another version of the generator in first test:

More videos on my channel...
Air Transformer:
6 meters cable 2.5 mm Cu solid
100 meters cable 1.5 mm Cu solid
Mini Tesla Coil 6-12V 0.5-7W/h
Analogue Voltmeter ~ ac
Power Supply variable 3 to 12V 0.8mA
One of the transformer coil terminal is grounded
High radiation in air if the case is not grounded but if is grounded the energy power decreasing...

Could this be what Hubbard coil did.
With your design and combining Hubbard coil design we can get a usable working design.

Since your device is outputting 600 volt ,try to make it 2000 volt range ,send this micro oven transformer 2000 volt side.
So that you can get 220 volt range ac in 1 khz less range.
Since you said your device is working in MHz range.
Stepping it down can be done use micro oven transformer try it and see

@justawatt  Interesting. Thank you.
I will first try to see how the capacitors react to this system, the classic but industrial or high power capacitors.
Secondly, I will try the version with a microwave oven transformer, but I probably need one with a very large metal core.
--------
I kindly ask the company representatives not to send me any more messages related to scientific trips, meetings because I am not traveling now.

justawatt:
Thanks for reply .
I am also facing this problem i am working with Don smith device.were my voltage is 250khz and 6000 volt range..
If i find any solution i will let you know.

Someone that develop and build RF oscillators doesn't think to convert the RF field back to electric current, if he had thought about it, there would have been commercial components to do this. They call it SWR instead and they don't want it because reduce the power in antenna. There are signal diodes 1N5711, 1N34A, (https://www.youtube.com/watch?v=y1rprh6rIT4) but they are made to conduct small currents because they are made for radio and television and not for power supplies. A specially cut solid crystal with a metal junction would solve the problem I think but these things are done in specialized laboratories. There are kV power diodes but they are also built for current and not for RF signal.
Honestly, I haven't heard of transformers that convert the RF field into electricity, but it's worth a try.
When I use my device on 9v or 12v batteries for power supply the AC alternating current component is very weak.
When I use it on 9v or 12v transformer the AC is very powerful but also the DC is high. The induction make the AC to bypass transformer rectifier and to be induced in my device. The good part is that the consumption doesn't increase with this effect but this is not the purpose to drain AC from a transformer.
I will try also to make a resonance circuit before output with industrial huge capacitors ~2 farads to get the f0 = ~60Hz
Some ones will ask: why you wont use a transistor with 60hz frequency in the Tesla Coil, but the magnetic inductance I think doesn't appear in a 60Hz resonant oscillator inductor only with fast pulses that give us higher freq.
There are some conic metallic pyramids with a coil turns on it that authors say it that can convert the field to current, i will search and post it another time. Something similar to http://www.rexresearch.com/grandics/grandics.htm
Also another patent:

Here is another rectifier:

And the patents are many on this matter.
I'm living near a war zone in north romania now and it's gets harder to work in research with RF and other experiments and my time become more limited but I will try to continue this work.
Here an LLC approach https://www.researchgate.net/publication/275041016_Multi-tank_resonant_topologies_as_key_design_factors_for_reliability_improvement_of_power_converter_for_power_energy_applications
Off course there are current commercial current converters but no one will go over 10000Hz.
@justawatt do you have a image / url with your test device? Thanks.
