im curious about the center hole... doesn't stans have a square hole so the square core is centered? or does that not really matter? i want one !!! lol

Is it me or does the VIC look like a series of Tesla pancake bifilar coils?

you are correct, as described in the tb the purpose is for each pancake coil to act as the plate of a capacitor with the delrin web as the dielectric. there is a whole lot going on in this transformer, it is designed to optimize the magnetic field/inductance properties, the capacitance properties and the resistive properties, and then operated at the resonant frequency of this configuration, and the core should be grain oriented electrical steel laminates.

I received the ferrite cores yesterday.  They fit the bobbins perfect.  I am now working to solve the inductance.  I have  .130 H on one choke segment with 165 turns.  The SS wire and the copper wire differ for inductance math.  My primary will need 178.5 turns to equal the .130H and my secondary will need 178.5 turns per each segment to match the inductance.  This will be a 14 to 1 step-up transformer. Saturday I hope to wind a working VicCoil.  Wish me luck.
