Your theory of the DC component of the highly damped output waveform charging 
the test plate is an intriguing one, but I can't see how the output waveform
can have a net long-term polarity (seconds), given that the primary ckt is driven
by a AC source, and therefore operates in each polarity mode half of the time.

Still, there may be some form of imbalance at work in the charging of the pri
cap by the HVAC xfmr resulting in a net DC component, although my coil uses
a pure DC primary drive, and I have not noticed any charging action on nearby 
objects (things may have been charging, but I wasn't looking for that effect).
I'll look for it when I run the coil in January, using a Keithley 616 and a
mini-ESVM made by Sensitive Research.

One quick thing to try, if you still have your experiment set up -- reverse the
leads on the primary, and see if the induced charge on the test plate changes sign.
