David,

One project gave a 36" spark and used about 8700 watts.  A later 
project gave a 35" spark and used 5700 watts if I remember correctly.
It would have given 36" if it didn't experience catastrophic breakdown 
of the primary coil!  But neither of these were magnifiers; they were
just regular tube coils.

I don't really think the tight coupling hampers the grid feedback, (in the 
magnifier experiments) but then again, it may have had some effect I
wasn't aware of.
