Malcolm,
Exactly. And what you have then is a Twin Magnifier, correct?

And this brings up another interesting point. What occurs at the base
of a "classic" Tesla coil secondary is NOT the same as what occurs up
the rest of the secondary. In fact, I believe that every Tesla coil
is a BIT like a Magnifier, in that there is a part of the secondary
that is (shall I say) like the Driver section, and the rest of the
"secondary" is reacting somewhat like the Extra coil. Maybe if we
made the base of the secondary a bit differently we could increase
the similarities and increase our arc output.

Sorry I messed up on my description of your coil, Malcolm. Guess it
wan't one of my better days. I whipped up that post between some of
my classes, and didn't actually refer back to your original post...
and my memory messed things up. Gads, I must be going senile!!
