   Malcolm -
   As far as I can determine you are the only one doing this type of
research so we coilers will have to depend on what you find.  I do not know
whether or not the secondary rings up with successive primary shots. This is
a possibility but may not occur. 

   By seven complete beat envelopes are you referring to the primary circuit
or  secondary circuit? Is it votage or current? Is it a dampened wave? What
does non breakout waveform mean? Is this from an operating Tesla coil? What
is the input wattage, operating frequency, spark length. I have lost track
of what you are testing.
