It kind of worked, with the windings connected as 8 turns in series and used on one side of the primary.
The idling current was higher than either of my ferrite chokes (E-core & ring core).
With a load (I only did up to 600W) there was no squiggle at the zero crossover.
Now I'm getting more cable lugs so I can re connect the 6 turns on my ring ferrite core into 12 turns.
From what I learned so far, more turns = lower idling current.
I'm still waiting for the little inductance meter I ordered from e-bay. I should then be able to measure what inductances my choke variations have.
As you mentioned in another thread, building an inverter from scratch is nowhere near as easy as it looks from the schematic.
