Reinhard, all,

I would add also that the stronger the streamers, the more the
corona is supressed.  In a weak TC I once made, in which the sparks
could barely break out (2 foot streamers from a 17"  toroid), there was
visible corona on the toroid when it was giving the streamers.  But in my 
stronger TC that gave 80" bolt-like streamers and arcs, I didn't see any
corona on the toroid.  I concluded that the stronger streamers pulls the
voltage down more, which seems to make sense.
