So here I am trying to recap where we left off. I can promise that this Forum will not disappear!! And will be for everyone to view. ..............................................................................................................................................................................................................................................From JackB,Rob, The only change that I would recommend is to replace D1 and D2 with two diodes each. I am a little concerned that one diode will not have enough PIV to handle the extra voltage from the bifilar winding, and will get damaged. Thanks for the drawing, now we have something to look at as we talk about it. JackReply from Me (FreeEnergine)Ok, So i'll purchase 4 diodes. I am a little confused with C, E & D for the Bifilar choke. As I wrap the two 40 awg wire that leaves me with four ends but I only see three connections (C,E,D) on the schematic? Do you also have a recommendation for the parts & specs we made need?

They are B and the two opposite ends of C and D. The easiest way to do this is to have both ends of the bifilar C and D end at the same physical location on the core. As an example, lets say that the green wire is C and the red wire is D. Connect the tail end of the green wire to the beginning wire of the red winding. This will be pin E. Now connect pin B to Pin E. Connect the tail end of the red wire to the ...
