What voltage do you use to power the flyback?  These B/W transformers were usually designed for a 150VDC supply.  Did you coil you own primary and feedback coils as is often done ? 

For the frequency, I think you are right, the primary resonant frequency should match, or be a multiple of the flyback frequency for optimal operation.

As for me, I do not have 5W resistors, but tons of caps, so I will make a driver based on the SR193 schematics.

Hi Tika,
I was using the the whole Portable TV as, is obviously without the CRT!! Just a small 12VDC plugin power pack of about 1 Amp. But it does not have the punch!!

for my initial test using a flyswatter circuit with a power source of 5 v dc rechargeable batteries  I can produced plasma on both flybacks and probably more can be handled using one primary source.....  to convert that plasma to a resonant coil then to a load will be my objective for now
tomorrow I will try to use a 220 v to   12 v ac transformer step down  then to the coils of the 4 flybacks via a 130 uf 450 v ac cap and a dimmer switch....  will use liquid nails for sealant   as shown on the yt

Hi Zcsaba77 to tell you the truth I'm still wondering how I did the setup of the flickering lights cause I changed alot of setups.
But yes as I think you already know if a cap is charged beyond it's voltage it can explode especially when using a ZVS.
In one of the posts King said to crush ferrites and do a form you need; did you do this? Do you use special type of glue?
Grumage can you please post your flyback schematic?
Thanks

Hi Guruji

What is it ZVS? These abbreviations not say me too much (ZVS, IMO, etc). Have not own aparatus, but I want in this year start with, now I just ask, and want to learn from experiented people

HI zcsaba77,

I too am in the dark with ZVS?  However IMO means, In My Opinion. I hope we can all learn, like you, from this more practical and nut's and bolt's hand's on thread

Cheers, Grum.

ZVS is short for Zero Voltage Switching  i.e. you operate the active switching device when the AC waveform to be switched just goes to zero voltage. This way the device dissipation could be kept at the minimum possible. Here is a link:
