Colin,
 
I had posted some information about Lou Balint's coil back  when
he did the experiment.  I don't remember offhand if it was a  magnifier
but much of Lou's work involved magnifiers, so it's very  possible.  
In any case Lou said back then that if the DC cap didn't have a  lot
of stored energy in it, then the thicker sparks would only be seen
when the sparks hit a ground.  But if the DC cap had more  energy
in it, then the sparks were thicker even for free-air sparks.   When
he ran the coil at a Teslathon, it had the smaller amount of energy
on the cap because some component had failed (or something)
just before the Teslathon.
 
Cheers,
John
