Huh, that seems kind of bizaare! I take it each of
your "extra coils" are wound in opposite directions? A
single line coupled input that causes arcing between
the ends of the circuit, now that seems like something
out of the usual! Most twins that we have seen
described are also complemented by each system also
having complementary primaries, but here you are
driving everything from one primary? Can you say if
the tuning (on primary) is the same for driving just
"one" extra coil vs two?
