Here, perhaps, is the nub of the discussion.
I was referring to a Tesla COIL, a Tesla Transformer.
Two (or more) Windings. Period.
IF one adds a a cap, making a resonant _system_, matters
are different. Commonly , the phrase 'Tesla Coil' is
used to refer to 'two coils plus a cap'. I was using
it (perhaps unwisely) to refer to the _coil(s)_ as such.
The _coils_ are relatively wide band. I can see no
difference between the coils of a Tesla system and
a pulse transformer.
(The discussion gets REALLY interesting in the case
of the Tesla Secondary, which lacks an explicit cap.
I suspect this is analogous to the occasional
discussion of secondary pre breakout (resonant)
and post breakout (less resonant/different (higher)
