As I again thought about the 5-VIC-coil layout I discovered an IMHO interesting point.
From the VIC-size and AWG-size, as told by Don, my guesses would be about the following Nr turns of the coils (Primary 100 or 200, Pickup 400, Secondary and both chokes 2'000). Sure the numbers are only guesses, but I think they should be in the right dimension region. What is really interesting is the fact, that the secondary has the same size as each of the choke coils.
If we now look at the wiring, that Don described (same as patent pic, shown before), one thing is very interesting to see: The choke coil voltage (of both coils in series) is certainly 2times as big as that of the secondary. This means, when the primary is energized, no current can flow through the diode. Only when the primary is off, and the chokes are swinging in reverse, a current would flow through the diode. This is quite strange.
Were the pickup windings also wound in 2 coils, as in the patent circuit? Is it just me, or are 400turns for the pickup not abit much...
Did the wire of the primary coil get out of the coil at two different ends, or at the same end of the coil. IMHO this would determine, if it had 100turns or 200turns (so if the ratio primary to secondary/chokes was rather 1:10 or 1:20).
Where were the resistors connected? I think you once mentioned, the 2 smaller ones (220Ohms, which look like connected in parallel) were connected to the pickup, and the big green one was connected to the primary. Is this correct? From the picture, it could also be, that all three were in parallel.
