First I'd like to say THANKS for posting all the 'scope shots.
I've not formed any particular conclusion yet, maybee I never will !
I do wish to point out that in your analysis of LCR filter for NST
your value for self-resonant frequency is correct,
BUT the series resistor of 1 kOhm will produce a "Q" of >5,
the filter is SURE to 'ring'. For your L and C you should have
5k6 or more per leg, or better increase both L and C.
All new data enjoyed ('fraid I'm currently more theory than practice!)
Bye ... Sulaiman
