You did do something right! You, obviously, built a first class rotary
capable of handling the quench times required for you coupling. Rotary
gaps
usually are only required if a coil goes to 5KW or above, are heavily
coupled, or are loaded with tank C and little primary L.
In the good ole days I got 6 feet out of my first really large coil
(large
for that time) with .025ufd and 13 turns in the primary. The system
used 3
12KV 60 ma transformers in parallel. It used 12 series cylinder static
gaps
which were fan cooled. Most anything works in Tesla coils as long as
the
design is synergistic.
