My experience: just on contrary.If detuning
excluded,another reason may be predominant.You use
high surge impedance primaries.Both coils I watched
(heard) here were tuned but had low primary surge
impedance (desire for high frequency not
efficiency).One had air cooled static gap,other asyn.
rotary gap.
