Incredible pictures, Steve.  I think I may try a version of this one myself.
The stacatto generator necessary to keep the plate dissipation within
reason?  This would be my first foray into a VTTC, I built mostly small
coils before, the idea of no spark gap noise is intriguing to me.  What does
the output sound like?  The classic RF sizzle?  Have you measured the
frequency of the output at all?  And why the 833?  Had you considered using
any other transmitting tube types?
Also, it may be informative to know your primary voltage .  Very nice
design.
