  I'll add more winds to the secondary today to see if I can get the same output as Geo gets. Which is about 120v, instead of 35v.  My goal is to obtain the same results as he is showing, without burning up the Fets.
I also work with what I have on hand, and have spent practically zilch on any of it.

Nick,

When you add more turns, put on as many as you can wind onto the yoke and tune to your desired load by removing turns until you achieve peak output.

   Sorry, it's not enough for you, but it's what I can do at this time. My meters have all fried the amp scale also, just like Geos. I will replace them when I can, so, that I can burn up some more.

   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

Do you damage your MOSFETs because you exceed their:
1) Gate voltage (V_GS) ?
2) Drain current (I_D) ?
3) Drain-Source blocking voltage (V_DS) ?

Dear Nick.

Bad news with regard to your FET's but one thing I failed to remark upon in the last 3 vid's posted is that my power transistors are only warm. In fact my base resistors get hotter!! And that is because they are under rated.

My own thought is that your overheating is being caused by the internal flywheel diodes. You must have seen the high voltages I am recording?? And in my personal opinion I really do feel that this effect is enhanced by the lack of diodes!! Now as a quick fix try adding a couple of fast high current Diodes externally and see if the overheating is reduced.

Cheers Grum.

Dear Verpies.

Please find attached scope shot of present setup as per yesterdays video. Ch1 60 V p/p. Ch2 output. Ch3 shows offset in relation to Ch1. This is looking across those very BADCSR's!!

I am sure that the Scope has a function to show the phase angle but I fear the Scope is far more intelligent than I am!! 

You will be pleased to learn that I have ordered some DECENT CSR's from good old ebay!!

Cheers Grum.
