Yes, the DRSSTC builds up much more energy in a short amount of time.
Also, it relys on 100 BPS or better operation to get good streamer
growth (same as a SGTC in that respect ).  The sparks look very much
like a coil running from a RSG.  You probably will need to run about
20 cycles since your Fo is near 100khz instead of 45khz like mine is
(i run about 9 cycles i think).  I like the 4040 counter ;-).
