The 8xa is the only replication which is charging the cell to a high voltage because it makes the
correct waveform which is a result of the full wave rectification.
You cannot charge a capacitor to a high voltage with ac, and that is the problem we are all having with the 5 coil vic.
Webmug, the vic being a pulse transformer is what I have also figured out.
And this is where the problems start. Pulsing a coil with a square wave and getting
a square wave out takes precise engineering and coil design knowledge. If even one parameter
of the coil is incorrect the coil will output ac. This is why replication is so difficult.
The vic is an adaptation of a D.C. resonant charging circuit!
BTW-WHAT DOES PAGE 1-1 OF THE TECH BRIEF CALL THE VIC?
