Hi All, Rich

  Increasing tank C (i'm assuming that's which C you're referring to), or
adding more primary sounds feasible, but the small problem with it is that
I'm using a low # of turns on the secondary, so a full turn puts me
completely out of tune (these things are picky!).  I'm tuned out around turn
4.5-5 I believe, so I'll have to try adding maybe 1/8-1/4 turn and see what
happens.  Right after I re-do my sync motor that got killed (darn
streamers!) I'll also try adding some C (put those caps I bought to good
use!)

 						Caio all!

I get the "single streamer" from my coil, and it's very good
to see it roaring. You need very still air, and no draught.
To prevent the breakout from the top turns, I think you should
try increasing the length of the primary and/or increasing your
capacitance.

  Hi all,

  I've been wanting to see the "single streamer" phenomenon using a
spherical topload (thanks Dave!), but here's the problem.

  I'm running a 3" diameter metal sphere on a 2" PVC form.  ~1000 turns of
32ga wire.  A 9/60 with 12.9nf.  Sync gap -at-240bps.  Once tuned, it runs
beautiful, tons of streamers, but a goodly chunk of them are coming off of
the top turn of the secondary. :(  That's robbing a lot of power.   Would a
toroid to help shield the top windings be possible and still get the
discharge from the sphere?

  Also, how in the world do you secure a foil-wrapped basketball to the top
of a secondary?  (don't want to try this on the 2" form, but maybe on the 4"
coil.

   												Caio!
