Guess I should reverse a connection: Roger Will go and
try that...

Since no secondary voltages seem to be apparent on the
inner spirals, 
an investigation as to what actual frequency might be
seen on the 
spirals was made by putting the same geometry of
spiral several 
inches below the process, and allowing that signal to
be scoped.
Scope sensoring of primary firing 
http://groups.yahoo-dot-com/group/teslafy/files/ALT/DSC00065.JPG

shows the position of sensor below the primary firing
at 10 volts 
variac to 15,000 volt NST. The rikety arc gap does not
easily allow 
higher voltage input without causing associated
problems,(arc 
spreading up wire and burning insulation, making
further operation 
shorted by that conductive path) but at 10 volts
variac the process 
is fairly stable, and can left running for long
periods. This would 
be only 1250 volts at NST secondary and a theorized
2500 volts max at 
Marx gap doubling of voltage gap.

9,000,000 hz signal from scope sensor;1volt,0.1us/div 

http://groups.yahoo-dot-com/group/teslafy/files/ALT/DSC00066.JPG

shows what the scope picks up at the surprising
voltage of 1 
volt/div, and the much higher frequency than was
suspected at some 
530,000 hz. This is about an 18 fold error so
something is seriously 
wrong. The sweep rate is at a very high .1 us/div,
showing nine 
cycles in one millionth of a second. HDN
