In my replication attempt of slayer007 SEC I have found that capacitive coupling between leads is effects circuit performance. It seems that the 60 turn coil wants to have some capacitive coupling between its ends (provided by twisting lead wires) but not too much. The following is what seemed to work best for me.

xee2,
   Did you try what slayer recommended?   Here's his post.

But you need to make a bigger L1 coil.The L1 coil I'm using is 3.25" diameter x 14" long 23ga. mag wire 4.80mH. You should also make the L2 adjustable so you can move it up or down the L1 coil to find the sweat spot. The L2 coil I'm using is a pancake coil 21ga. plastic coated wire 9 turns .05mH

for the ones that GOT THERE TRUCK STUCK IN THE MUD!

TRUCK AFTER TRUCK THEY ALL GOT STUCK! 

conola seed for traction !  some of the best at that !

; )

say eh eh yah!

GO CANADA!

IT may be more fruitful to put a capacitor across those leads - something very small, because this is effectively what twisting the leads does; you may find you can get more benefits than you would  by using a capacitor than twists might allow for.

I missed that one.

Wonder what is the input/output ratio of the induction heater.

In the big induction  furnaces that they use to melt  iron .......the iron that they are  melting  is like  a one  piece  winding
