Well, thanks to that single sentence from Laurence in his last
posting I finally got out of the nasty problem!

"as long as the coil wind direction doesn't change at the tap point"

and, suddenly I realized that it DID change in direction.
So, I imidiatly changed one half of the test coil, and voila it worked!
Less current, more output, and les harmonics.
Second harmonic seems to be very strong effected by the (470nF)
capacitor at the tappoint.
When adding extra capacitors there is a point where it is optimal rejected.

Thanks so much Laurence!

Hopefuly I'm back on the right way now.......
