Could this "special" mode be a case of spurious
oscillations?  Certain vacuum tube oscillators, and
now MOSFET oscillators too, are susceptible to such
operation if the grid/gate leads are positioned in
certain ways or the leads are too long and pick up
spurious excitation.

Apparently the modern terminology for this
condition is "parasitic oscillation."

Thanks SeaMonkey,

your thoughts are very much appreciated, i guess you are right, something is causing this parasitic oscillation.
It however seem to cause this parasitic oscillation only when using a ferrite (yoke) coil (high inductance) as with an air coil it produces nice stable sine waves.

  I've been trying different things out on my Akula air coils set up, along with the HV pulser.  As I'd rather have a HV pulcer that is directly connected to the output coil of the air coil, instead of as an Exciter effect. I wanted to see what happens when I connect the Joule Ringer circuit from the rectified DC output source that is coming from the yoke's three turn coil, through the rectifier diodes, capacitor, and to the small DC bulb. I connect the joule ringer input to the small DC bulb, and output side of the ringer to the air coils, through a diode, to convert the AC to DC.
  I've also managed to be able to light a single 110v 100 watt bulb fairly bright from the air coils output now, but not more bulbs, as before, yet. I've also added some more turns to the air coils. I notice that now the superimposed DC pulses can be felt at the mosfets, battery rails, and most everywhere on the circuit as well. The ringer is drawing its input from the induction circuits DC output (rectified from the 3 turns yoke coil, as Akula has it in his second video device.
  I'm still working to tune and adjust things, but the fets are still getting hot, although at times for some reason they don't get hot. This I'm also looking into.

Still fiddling around with the mazzilli special mode thingy.

I tried to compare both the normal mode when using an air core and the special mode using the ferrite (yoke) core.
Comparing the both MOSFETs drain/gate signals.

Below you see 2 screenshots of the both modes, first the normal mode using the air coil:

yellow = drain voltage MOSFET 1
purple = gate  voltage MOSFET 1

blue   = drain voltage MOSFET 2
green = gate  voltage MOSFET 2

Second screenshot is special mode using the ferrite coil:

yellow = drain voltage MOSFET 1
purple = gate  voltage MOSFET 1

blue   = drain voltage MOSFET 2
green = gate  voltage MOSFET 2

Any idea anyone what this ferrite special mode is caused by (parasitic oscillation)?

Itsu,

Interesting waveforms from your latest experiment into the 'special' mode. Please show how you wound the primary of your yoke.
