NickZ,
i would estimate at 40% compared to normal grid operated.

GeoFusion,
yes, the other yoke halfs ring like a bell (3.842KHz) when tapped.

Some additional measurements, now using a full battery and a 150W bulb
In "special mode", the current pulsed up till 21A at 3.8KHz using a 0.1 Ohm resistor
Also some temperature measurements where taken.

Hi all,
Data on the yoke is:

Clips removed, insulated both halfs by black electrical tape 1 piece each side.
Hold together by 2 wraps of electrical tape on top and bottom.

secondary (black wire 1.5mm2) 36 turns / 430uH
primary   (blue  wire 2.5mm2) 2x 13 turns / 2x 40uH

cap 376nF
choke 220uH

It seems to work in 2 modes, the "normal mode":
Supply 12V (11,8 when operating) pulling 550mA giving 104V p2p sine wave at 10KHz

and in "special mode" after fiddling with the 12V lead:
Supply 12V (11.5 when operating) pulling >1A giving 576V pulses at 1.490 KHz

When time permits i will make some more measurements (current in "special mode") and increasing the wattage at the load etc.

Dear itsu.

I was really glad that you were able to get 104 V P/P from 11.8 V Dc input. That confirms my own findings.

I enjoyed seeing your video and I now feel that this phenomenon is due to the physical characteristics of the Ferrite core. The Yoke being of a larger size but thinner may well contribute to the "Ring" that you were able to induce. I also noticed the waveform appeared to be "Spikey"?? This would give credence to Verpies statement regarding split cored transformers.

I eagerly await your follow up. I'm afraid I cannot experiment further as I do not have a Television yoke to hand.

Cheers Grum.

PS. this post placed between itsu's!!

We cannot be sure that 3.842kHz is the yoke's acoustic fundamental standing wave frequency.  The 3.842kHz that you measured might be the transverse acoustic frequency.

Anyway, IMO this "special mode" is based on magnetoacoustic phenomenon (initiated by magnetostricition of the core), your goal should be to match the LC frequency of the primary windings to ½ of the acoustic fundamental standing wave frequency (whatever it is in reality).  Once that primary frequency is found it should be noted and aimed for throughout the tuning of the secondary winding (described below).
Note, that primary LC frequency is heavily dependent on the capacitor across the primary winding and on the load across the secondary winding. 
This Mazzilli type of circuit is actually a Load Controlled Oscillator

At the same time the bulb's brightness will be subject to the Maximum Power Transfer Theorem and the only way to match the impedance of the secondary to the impedance of the bulb without a lot of measurements and math, is winding the secondary winding with excessive turns and subtracting them one by one, as the circuit is operating (that can be done with a sliding winding wiper, like in a good old Variac transformer) while observing the trends.

I recommend that you try to bring large magnets perpendicularly closely to the core and experiment with different gapping of the core halves (avoid acoustically dampening materials between the halves). 
Finally, adding a HV capacitor across the secondary winding to create a second LC tank might also be attempted in order to create a phase offset between core halves.  The STAAR Yoke Device had a capacitor like that across its secondary.

P.S.
In Mazilli circuits the DC choke should be as large as possible. That should also be true in your circuit if that choke is not where the magic happens

The scopeshot below is supposed to represent the current (red) and voltage (yellow) across a resistive load (an incandescent light bulb).

If the load is truly resistive then the current waveform should have the same shape as the voltage waveform, since the latter is the cause of the former. Disregard that one of them is inverted - that's only caused by scope probe placement, and the difference in vertical scale that's caused by the lack of amplitude normalization (a scope setting result). 

What's most important is that the shapes are different and they would stay different even one waveform was inverted and normalized to the other.  In other words, when the scope is set to XY mode, the voltage and current signals should form a straight line (a line inclined at 45º after amplitude normalization) - yet they do not.

The current waveform shape is so different as to have features that the voltage waveform does not have at all - such as the HF spike in the middle.

Maybe the the CSR is inductive, or the bulb is very inductive or the scope probe is picking up some EMI.
Try switching the scope to XY mode and moving the scope probe cables around, to see if you can fit the voltage and current signals on a straight line (tweak the voltage signal Y gain to make a 45º line).

P.S.
When measuring voltage and current simultaneously, the ground leads of both scope channels should be placed at the CSR pin that is connected to the load.  This does not matter very much now, but as a matter of principle we should strive to measure voltage across the load AFTER the CSR in order to disregard any voltage drop and power loss that the CSR itself might cause. 
This is especially important when multiplying the voltage and current waveform in order to obtain instantaneous power delivered to the load.

Hi Itsu,

When you put split of core inside of primary coils it is whole another story..
Just try to make 1:1 core winding configuration like Geofusion has in http://www.youtube.com/watch?v=CRJBEhxmXxQ so the secondary windings will be in half-choke mode and also prepare bank of capacitors to withstand lots of reactive current as it loads them like spark discharge in N. Tesla circuits.

Cheers!
