Aha!     (That's "aha number one!")     It does involve earth-resonance!

Aha number two!   And the labels in image014.gif above look
accurate according to what I've figured out about this device.

So it looks like my chain of speculation wasn't going down a dead end
after all.  The main terminal is shorted to ground, but done via low-value
inductors.

Ooo, I hadn't seen that one before.  If the two different frequencies are
closely spaced, then the TC output will be AM modulated with a slow sine
(a beat note between the two primary frequencies.)   And so the voltage on
the "C2" electrode will in sequence fall to zero and then rise to twice
normal output, which fires the gap at the low frequency.  That would
*greatly* aid in quenching that arc.  (I'd wondered why that arc would
reliably quench between pulses, yet quenching seemed to be required.)

And...  WAVE COMPLEX.  Aha number three.  I don't often meet anyone who
has the smallest idea about the meaning of Tesla's phrase "wave complex,"
or whom even suspects that "wave complex"  might be a key to some of
Tesla's major (if undocumented) discoveries.  If Tesla had earlier
succeeded in creating "Victorian spread-spectrum secure comm,"  then this
multi-resonant magnifier coil looks like an attempt to "encrypt" the
Wardenclyffe power output so that only a desired receiver could benefit.


I strongly suspect that much of Tesla's work was guided by a certain
construction habit that modern hobbyists haven't reproduced:  using huge
primaries, large enough to stand inside.   And then doing hands-on
experiments with multiple secondaries while the primary was running.
What do you get with two, three, five secondaries?   What if they're all
identical?  What if they're all different by the same amount?  By
differing amounts?
