Tuning, and a bigger toroid, a large enough toroid will result in a single
long arc at a time . . . Also, read the next few answers, they will help

Your secondary should DEFINITELY be grounded, well grounded. However, not
to your house's ground, but to a seperate grounding rod several feet
underground. A strike rail is also a good idea, it will prevent damage to
your primary circuitry by letting the arcs from the secondary go to ground
rather than into the primary.
> 3) I'm getting a lot of inter-secondary arcing... how can I correct this?
Too much coupling - raise the secondary up above the primary some more, this
will also prevent primary strikes. Your secondary is definitely big enough
to handle the power.

Are you sure you have them in parallel? Cause if they are, your capacitance
is 0.34 uF . . . maybe you just mistyped something.

He he he . . . isn't campus security great?
