Akula0083 30 Watt Self Running Generator.

Hey Dave
Do you know the frequency range that mazzilli can reach? Especially without tank capacitor at the primary just with the capacitance of the mosfets, what would be the maximum switching frequency?

Thanks

Why you need know core resistance?
By way, I have exatly core like in akula video, I get it from flayback transformer of monitor CRT.

Different core materials have different resistances. I am just trying to determine what type of material is in the cores that I have on hand. There is no numbers on the cores.
As alwaysw, thank you and have a great day.

Yes it can be done like your thinking with a little help 
I have not finished building this, so no guarantee's 

The connection o negative side from Mazilli should pointing to that diode bridge instead. Then second connection from diodes AC side to the negative. In other words - the tranformer primary should be connected as choke and its output looped back to the input.
Otherwise you have conventional transformer circuit....

Here's where the circuit gets a neg boost to drive the primary's

Hey Jeg
Not sure, the cap and coil turns regulate the frequency,If I remember correctly mine ran at 21kz with 10 turns 18 ga on each side with .68uf 1000v cap.
Its been awhile since I ran it, hope to get time to put it together again this weekend.

I havent ran it without the tank cap, the drawback with the mazzilli is the high amp draw but I hope to bring that under control.

Something interesting that I intend to explore more, I wound a toroid like a joule thief and hooked it to the mazzilli, the joule thief coils wouldnt let the circuit push current through so the amp draw was nill and was getting some serious bemf. magamp.
