Hi ...

I did a few more tests using the previous setup, with
the 1.8 uF / 60 kV cap between the bottom of the
secondary and ground. I have a normal AC tesla
primary, and a well filtered DC supply to energize
the big cap.

Using only 4 inches of spark ( mindful of GL's and
Mr. Wysock's experiences ) I measured 0.5 ma of
DC being induced in the DC cap, with the DC supply
disconnected. Positive was towards the bottom of
the secondary. This varied with the intensity of the
spark, as one might expect. It took 14 seconds on
an average to charge the cap to 1000 volts.

Next with the DC supply hooked up, nothing much
happened until at around 10 kV, when periodically
one of the sparks would become much brighter, much
fatter - around 1/4 inch - and give off a rich sounding pop.
The end of the spark at the copper ground rod had 
a greenish tinge, and at the aluminum torus was 
whitish, indicating probably some metal erosion.

I'll crank up the power a bit tomorrow, after carefully
unplugging anything sensitive.
