Hi Gary,

I've reported previously on an envelope effect.  It seems that
rising envelopes are more likely to produce the straight sparks,
whereas, decrementing waveforms are more likely to produce
branched sparks.  I base this on some tests I did with a VTTC.
Of course heating or other effects may also be a cause.

Cheers,
John
