Magnetic Resonance Devices based on Don Smith Concepts

Gentelman,
   That particular Bertonee NST was manifactured WITH a center ground tap - just like all bulky non swithing NSTs have(the big ones).
However appeareantly no other company is manifacturing switching center tapped NSTs for whatever the reason.. ( makes me wonder why)
NST ground was connected to Earth ground (right at NST terminal) and then to the primary LC tank ground via a spark gap arrestor. I have a switching HV traffo from amazing1 driven by h-bridge and center taps grounded. No lucky for me Primary LC has very high impedance to volts because LC is very capacitive (wich means will take amps but will resist volts) so I have no chance of getting my primary LC resonating from this NST because of severe impedance mismatch....
For exemple my NST has impedance of 10K ohms+ @ ~50Khz while its trying to feed a primary LC that has impedance of less than 10 ohm...    10000 ohm VS 10 ohm - impedance mismatch will not allow any energy transfer - I simply cannot make my NST draw more than 1 amp.. Then I took simple LC having impedance of approx 6000 ohms @ 50khz and sure enough -  NST will draw up to 4 amps - because there is efficient energy transfer to LC because of somewhat matched impedance) and by feeding 800 VDC I could get it to resonate up to 7000 volts p-p and cant allow any more because It would exceed my HV probe limits.
Just a short insight from my experience. Hope it helps.

^{Good eve all...  putting my best foot forward I would suggest the looped red wire for L-1 is as suggested a virtual ground "type", Not founded as a node but as a center-tapped in essence ground. however (This may very well be Grounded by the plug though).  Not be belabor the point though, I see this as the direction of flow of the circuit.....
We are grounding one side of the circuit with through which we pulse the two capacitors via the HV diodes; "the hot side" Then feeding the L-1 red wire ??    y the lightning arrester ou get the idea!}   shrinking ok back again? what was that?
Which in turn completes the loop. 
Draw this on paper just as it is in the pictures....!  This to me looks like an LC circuit as long as the frequency stays above 20Kz this should resonate if you get the numbers right.


I haven't built mine yet, this is how I see it though.

I'm still waiting an answer for the message I sent you yesterday. I want to know the name of the company that builds the yellow capacitors. In the picture I can read Ctision or something similar. It's not enough clear.
About the NS Transformer, I've read some information about to prevent the use of classic models. In the pdf that gyulasun posted here (http://www.rexresearch.com/smithdon/DonSmith.pdf), if you read the end of page 83 and the beginning of the 84, you can see some recomendations about not using comercial NS transformers and the author also recommends to build your own one. This recommendation, and also your own one about the center ground tap implies that the best option is to build our transformer. In amazon or other online library anyone can find a series of books called "... for the evil genius". There are about 15 different books of that serie. In one of them there are schematics to build your own high voltage high frequency power source.

As you say this is an LC circuit. Refering to H.Torres you can read and we know that "when the transformer is in resonance, the impedance is zero". So adjusting the numbers right, you'll have a LC circuit.
Where I've still doubt is in the 2 AC connections that are in the output of the NST. Each of those 2 wires has 1 diode. Then, those 2 wires becomes one  ?
In the picture that I've attached you've some similarities with other non usual configurations coming from other circuits different to Don Smith's one.
Someone with more electrical experience maybe can obtain some ideas while viewing the circuits.

This is the driver circuit of the operation here is how I get it.  This is the part that starts the ball game off.
I have not yet built this circuit.
I simply see it as an inductance and capacitance circuit that is grounded causing a closed circuit that may resonate.
The capacitance is the tank that will set the speed of oscillation when the inductance is matched to this capacitance over 20 khz it will resonate at very low cost of consumption.
"No resistance"


Testing and discovery are the only ways to be sure..

Do you read what you type..  because I dont understand most of your posts... a little out there... and hows spark gap will affect oscillation speed? It could affect time at what LC will be charged by DC source before spark breakdown occur but not oscillation speed.... based on this I think you might need to read and learn more before you post

Custom electronics Inc. NY I believe. Great mica caps. Not cheap.
