P.S. Finally ordered the FEG book, so maybe that will privide some insight. I'm sure it will

Yesterday I was testing the real diode's function by using them in paralel, is amazing and obvious his real function, the real mathematics model of diodes shows clearly a drop voltage in the K-A junction so in the practical this limits the max power that our power coil able give us in Back EMF way. Normally this voltage drop is about 0.6 volts, but can be higher when the junction has no recovered of inversed voltage as Bedini's Osc case.
I have tested this diodes:
1N4001 x 4 in paralel: works great, capactitor charged very fast.
1N5404: voltage drop very high, in paralel is far away from 1N4001
1N5408: equal to 5404. very big can be difficult for a pcb.
1N4148: it's high recovery, but voltage drop......
The 1N4001 x 4 in paralel, it's highly necessary in Bedini Osc, when you put diodes in paralel voltage drop appearentely get to hide.
The diode connected Base-Emisor, normally 1N914 can be replaced by 1N4148 because is high recovery and is possible get higher RPM's. I had no tested yet.
