  Grum:
   The reason that I'm blowing Fets is due to my way of connecting the secondary coils output to a full bridge rectifier, and then further on as a feed-back path to the 12v battery. Although I've been able to do it previously, by providing the battery with a 14v feed-back, the result was less than brilliant, this last time around.
No worries, I'm already making another circuit using different Fets this time, both mounted on a different heat-sink/fan set up for better cooling, with the two Fets isolated from each other.
  Please add the diodes to the diagram that Geo posted (below), and I'll be sure to include them on the current oscillator that I'm working on now. Or just explain where they should go.
Thanks,

Nick,

You are wasting your time trying to loop-back to charge a battery that is at the same time discharging. You need to store the loop back charge and dump this to the battery whilst it is completely disconnected from the device. Switching is needed for this. Also, your choke should be labelled uH (Henries) not uF (Farads).

   The idea with using a bigger battery is not what I have in mind, as the battery is only for kick starting the device, and not to be used as a "run battery"  for as long as possible.
This is once the self running aspect is obtained. I know that using more batteries, like 24 or 36 volts, would give higher outputs, but the transistor heat issue is not resolved yet, even with a 12v battery.
  I may use another battery soon though, as I'll be buying a new one for my car, and can possibly use the old one for this, or not, depends.
  Last night I blew another (one or both) Fets, testing for the feed back path.
That's life...
 
   
  Geo: What was the part number of your best working Fets, again?   
I'll see if I can get them at Radio Shack. I hope that they are cheap, as I may need a Kilo of them, the way that I'm going

Hi Nick

Yes haha Igor's induction cooker project also did it with two ground. as you can see there is alot more to try out !
Srry to hear about your Fet's tragedy. 
Yes more DC input like 24 or 36, i have tried on the roundcore to and gives more output and more brightness, maybe double or 4x the output.

The Part number of the fets I used in original is IRFZ34N Fets, they are not so expensive.
Be careful to what is applied to the output coil. as it can easily kill the circuit easily.
Try to place a 3de coil where there is space left for it on the yoke to wind.
try 5 turns and place a halogen between the leads.
You'll see it in my vid, around 0:08-0:09  or around 1:10 to 1:11.

I could help you with the Diodes to. But Diodes I used with larger Fets like the IRFP250's and IRFP260's.
My newer Circuit outside uses Germanium Diodes.

Give me a sec I will make a new Drawing for you to try out.

"Edit"
Hoppy:
that is my fault, putting uF instead of uH, srry and thnx for letting me know.

Cheerz~

Dear Nick.

I hope this clarifies?? 

Cheers Grum.

Hi Nick and all 

@Nick: I have modified to first pic to where you can put Diodes to help. Should try out it.
        See how the Diodes are On the same line as the resistors. But be careful.

2nd Pic is for Higher power but, this one stays cooler though , way cooler then first one.
But the Mosfets are of Higher Value. IRFP250N or IRFP260N.

The second Schematic I used for the first time one the RMG. But also tried it on the Roundcore and Does a great job.
Works awesomely. But afterwards had to reinforce it yet again.

Hope this helps
