Hi Malcolm,
Sounds like the rotary gap spacing was too wide, or the electrodes
happened to present at the wrong times.

This effect may be related to a high break-rate, and lower voltages?

I agree, my secondary resonator unloads pretty quickly, maybe within
little more than one beat envelope of time.

I was unaware of this observation by Dr Resonance...most intriquing.
Yah, plenty o' questions for sure,
