Not really,  I'm merely saying using a higher input voltage is a *one*
relatively easy way to increase spark length.  I'm not saying its required.
I agree with you

I'm not sure of that.  There are a few people who claimed to have gotten
very large arcs (such as the guy with the 6 ft arcs), but I have yet to find
any detailed information or
descriptions of these coils or pictures for that matter.  And i'm sure all
of us here would like to get more information on these "huge arc" sstcs.
There would definitely be a lot to
learn from these "huge arc" pioneers.  I wonder if there is any way to
contact these individuals and get some specifics of these coils.

SOLID STATE IS THE WAVE OF THE FUTURE!

Of course, try telling that to the big program managers here at work
(regarding solid state radar transmitters). . .
My team at work however did just finished designing and building a 300kW, CW
X-Band radar transmitter.
