Very happy, the 2nd 3 stack transformer with 14 turn primary has exactly the same AC input to output voltage and power reading on the Variac.
Found some different low cost toriods for the chokes. A larger hole and similar size, they needed an extra turn for the same inductance, I still have to test saturation current to be sure they will do the job, I can always use an extra core if needed at the price.
Picked up the cable for the chokes this morning as well as the Primary winding for the 3 stack transformer, it took just under 8 meters of cable for 14 tight turns.
EDIT: Now running in the test inverter, and with incorrect lower value chokes it's idling at 23 watts @ 241vac, hopefully I'll get the chokes tested and running tomorrow before a forced lay off, and hopefully only for a few days
