The primary-secondary phasing question is important in systems with very
tight coupling, ie, a true resonance transformer with 0.6 coupling factor.

There is no difference in phasing with loosely coupled circuits, ie, true
Tesla oscillators with typical coupling factors of 0.1 or less.  We have
tried it in various combinations and only noted a difference with "extra"
third coil systems running 0.6 k factor on the first two coils.
