no despite the sarcasm you did seem to got the hang on it

By conecting the secondaries out of phase you get at phase shift of 90 deg see scope shot.
yellow is output

Excellent work, I would like to see the schematic that you used to achieve that. Since I've seen a lot of controversy regarding to  Partnered Output Coils!
Thanks

Simple I just wound it as you original circuit 7.5 FT for primary but this goes on last over one of the secondarys.

the 2 secondary are wound in opposite directions  ie start like this ---)))))))))---- then the other sec like so ---((((((((---- so they are out of fase
Then use a scope and a sig gen to find resonance of whole core and winding. other wise you get nothing across the secondary.

caps just attenuates things when i tried adding to lover freq, so resonance isn't alterable for me.

AlienGrey Thank you! that image is enough for me. Now...! can you put the scope shot including the two secondary under load? It would be very helpful and enlighten the darkness that covers this forum.
