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.
