Thanks Totalas and Tika for response. Yes Modern flybacks have diode in them as said. Today I hooked the Flyback to the cap in series to the coils and then the SG to earth. Light was very bright on bulb but was flickering. Maybe if I put alot of ferrites in coil I hold voltage and stop flikkering.

Cool, those are encouraging results indeed!  Just a thought: if the HV is too high, a lot of power will escape to ground though the spark gap, the transistor will get very hot and the DC supply may collapse, that will cause flickering.  Did you check the DC supply to the flyback?  If it is collapsing, you need to either get more power available there, or lower the voltage to limit the loss though the spark gap, or a slightly wider spark gap if less than 1mm ? 

Good luck!

Thats good news
more exploratory experiments to follow and hope to develop a hybrid if not a so FREE Energy which is so elusive    lol
I tried to use two flybacks  and 18 ga 10 T around both ferrite cores ..  These are in series with a relay spark gap   - 2coils in series for each flyback
then to a flyswatter (4.5 v dc supply rechargeable battery)   . the two output from the flyback are charging via a spark   plasma to  a ferrite core with center tap bifilar coil shorted to earth ground . the bottom and top are connected to a dc cap 33000 uf 63 v dc  in series with a diode closing the loop ( energy amplification thread  gyulas latest circuit)
the top e core is wound with 400 t 23 ga   and produced 40 v ac with led lamp flickering with earth tap connection on the body
the iginition set up for a 220 v ac spark gap...... I will try with a flyback  in place of the ignition coil ( new one cost 400 HKD)  flybacks cost me only 20 Renminbi  so I will buy more
lets simplify and amplify...  my e core is 4 inches in length and 2 inches height for half e core.....
If TIKA can make a control circuit for the hv side would be better
Check also Peter Linderman plasma mod where he amplified the spark into plasma by combing the positive dc source via a 12000 diode from microwave oven then to the output of the HV  ignition coil...
Very simple design  , he has a 555 timer circuit pulsing a 12 v dc relay,  2  no contacts   one side is upplied by variac  the center is from a photo flash cap  and the other side goes to the ignition coil  all are isolated and the supply from charged caps pulsed are the one supplying the ignition coil
instead of variac , we can use the flyback, to charge caps, then to the primary coil   / earth combination,  the load side is History.......
gurugi can you make a simple sketch on the lamp   thanks

Hi I'm using a ZVS as driver. SG should be very close. Beware  not to explode the cap 
Today I tried alot of setups but still wondering which is the best.
I think cap should be in parallel though with flybacks like all Tesla coils.
Ok I should see more on this.

Hi Tika and all.

I have been looking into replacing my Ferrite Sets today and got this spec. I have attached below. What came as a shock to me was the abscence of Iron!! They do have quite a high permeability but will they be any good for this project? They are really cheap though, under 1 GBP each!!

And on another experimental observation with just my basic HF primary and 30 turn secondary. Up till now I have been using a small B/W television Flyback transformer with it's own oscillator drive (16KHz) output probably about 6 Kv rectified. Getting a dim glow in a 240V 40 W incandescent lamp.

Earlier today I replaced the above with a 5Kv 50 Hz AC Ignition transformer. Slapped on a couple of HV diodes and the light output was amazing.

From this simple experiment IMO, two facts have emereged. First you need a strong healthy spark. And I noticed while the Spark Gap was running I could hear the underlying 50 HZ base frequency but as this was going on, audible fizzing of the SG saw the light intensity increase with the fizz. So even though you rectify your HV AC the underlying drive frequency is carried through. So IMO a High frequency voltage supply is also a must.
