Hi Gustav22 and all,

I mostly agree with your calculations. In fact in my case, with 6" ring (5" medium diameter) the 105KHz is very good indeed. Some times ago I reached your same point about the 15" ring comparation... but it's still not practical to deal with such high freqs, on the other end I don't think that SM did use any.

I spent most of my time in saturday playing with the beast and I succeed into not burning any mosfet by just planning accurately the tests themselves and.....using the power supplies with extreme care.

Mainly I wanted to ascertain the freqs to use, lot of work in this sense and found many possible solutions: that's a problem...as it's still very, very difficult to make a choose. I also checked it again with CHORDs (base Major 4,5,6), this latter has been possible as not running with synched oscillators....so for the first time I've been able to get from a CHORD similar output to that obtained using standard harmonic relationships: very interesting as even if the 3 freqs are not timely correlated I do obtain as well pulse superposition!!!!. So this is a prove that what SM told has "...use harmonics or chords..." is defnitly true.

In the attached pics you can see: multiple pulses summation and single superposition detail. The amplitude in this case is low as the test as been done with PS set to only +15V.

@Earl,

I forgot to say that I did as well tests using 4.4MF (plyester cap) as levelling capacitor: the slow power pulsing still exists and it does not vary. Unfortunately at the moment I've no more high voltage caps so I can't say if using an higher capacity would have a different  effect.

Hi Roberto,
thank you for the update.
You say that you used the chord major, where the frequency ratios are
4 : 5 : 6 .
this is the same as
1 : 1,25 : 1,5
and same as
0,666 : 0,833 : 1
I just wanted to write this down here.

@Gustav22,

Yes it's so. The Major chord test has been run using as base frequency 35000Hz.

@all,

do you want to see what happen to output waveform while 60W lamp-load is connected?
Just have a look at the following pic (DSC_0086) which is self explanatory.

Note: the limiting is only on the positive side as for this test I connected only one diode. I did it of course also using a bridge rectifier and the limiting does appear on both sides.

@all,

as requested by various guys I've annotated the already posted

I have some awesome resonance from my new mini Tesla, check out the photos in Dr. Stifflers thread:

P.S.Ã,  By the way, nice work there Roberto, 3 sisters and a lucky guyÃ, 

the mini-tesla has it's own link now in the Tesla category:  http://www.overunity.com/index.php/topic,4070.msg75778.html#msg75778
