Somebody told me me that the VIC 6-1 might actually be the the "amplitude control circuit" for this bifilar circuit . It would be great to see with a phase meter , if there is actually some current phasing going on with John's connection as the frequency is changing, I believe there is not , so I wonder if this is not just some advanced form of power supply .
It is true that the waveform is the same but that waveform will always be the same when you have capacitance in the circuit , its nothing telling at all .
Also I wonder why go through so much trouble when a normal rectified transformer would do the same thing , perhaps a question of efficiency ?
But then theres also the issue of how it is you should connect the VIC 6-1 to this bifilar , it all makes no sense , the bifilar is grounded but is also connected to the 6-1...
Also , Kinesis , plz confirm that you are indeed getting some unipolar pulses with no other diode besides the one before the positive red choke and inputing unipolar pulsed dc on primary side.
