hi hoppy,

If you take a look at the mosfet datasheet the voltage needed to turn on the gate is 2volt to 4volts.I have proven this via my previous video 1watt HHO ver 1.0 using only around 4volts supply to power this same mosfet to split water.
1Kohms resistor is needed to limit current to mosfet and zener diode 4v8 at the same time for this HV circuit.
If there is no heat detected on any components while running it is not an issue related to current overload at all.

Yes, but you are severely limiting the continuous and pulse current, which may be ok for your application but not necessarily good advice to others using this oscillator for other applications.

hi itsu and everyone,

As promised i have used my favourite 47N60C3 mosfet rated 600volts to replicate/modify the Mazzilli Osc circuit.
I have just uploaded the video to proof that it works-http://www.youtube.com/watch?v=vsJQ84DhODk

Thanks for your work/video magpwr.

offcourse we are using a 2x27 (or so) turns primary around a yoke without sparkgap etc.

I have ordered another bunch of those MOSFETs and will retest, paying attention to  the cap, first being in the 600nF range.

Also a high wattage drain current limiter resistor could prove handy.

I agree with Hoppy that the gate resistors/zeners (470 Ohm / 12V) should be adequate as the specs speak of 20V gate voltage.

I will however keep your values in mind in case the MOSFETs still pop.

Regards Itsu

  Hoppy and All:
   I have not used the newly bought Zeners yet, on any of my previous Royer circuits, as I have not found adequate Fets to go along for the job, yet, and I'm still looking for some.
  The only zener that I could find at the shack were the IN4742A, rated at 12v, and current rating (lz) of 21mA. So, they may be too low current for this purpose, as I would not want to burn up new Fets, as well.
The Shack does not carry the IRF 260, Fets, either.

  I would like to work with Mazzili circuit, as I do have most all other components, ferrite cores, and such to do so. But hopefully using a yoke core, instead. So, a Mazzili with a yoke core.
  I was waiting for Geo to lend a hand, and maybe we can work together to improve the performance, as well. Especially the feed-back path. As without that, we don't have a self runner. 
  It may be,  that to see some real magic with this type of circuit, over 500 watts of input power needs to be drawn (like Igor is showing), to obtain 2000 watts output to the bulbs. Single smaller incandescent bulb circuits may not see much advantage, or gain, and can even use more juice than the circuit will produce, as in Hoppy's case.

The IRF 620 were the Fets that worked for me, although in my set up it only gave me 32v output, using a 12, 4.5aH battery, but still was able to light two bulbs fairly bright, with no shocks, anywhere.
  If you Hoppy, like Itsu aren't seeing the cold electricity aspect, then something may be wrong, as I certainly do. And at only 30v, I was able to light up to three bulbs, although but dimly, using my Akula yoke , which does light a 100watt 110v bulb. So, some core tuning, will be one of the next tuning aspects to be experimented with, as well.

Nick,

At the risk of laboring a point, you may continue to smoke good mosfets without gate protection zeners, especially if you increase supply voltage above 12V. Insofar as juice is concerned, I've seen no evidence as yet that Igor's devices are displaying any real magic in terms of more out than in. How did you deduce this?
