The magnifier configuration still only has a primary capacitor - at 
least the ones I've made do.  I'd argue that most if not all coils 
operated in 0.1 - 0.2 k range are essentially free resonating as the 
highest coupling by far occurs in the vicinity of the primary. The 
scope seems to back this assertion up - i.e. it does not show a 
change in oscillatory mode when the gap quenches.

Malcolm
