In my first sonotube coil I was silly enough to use
some 1500 ft of 14 gauge wire, leaving soldered joints
between the 500 ft lengths. The coil produced weak 2
inch arcs, and was probably mistuned. But when the
ending wire was brought close to the first bottom
solder joint, it produced a much stronger white arc.
One would think that since 2/3 of the wire length has
been cut out by the shorted secondary arcing loop,
that the vibration gained by the remaining part of the
secondary should be a harmonic, vibrating three times
as fast.
