Nice, the spark output looks and sounds a lot like some staccato VTTC's,
as someone on 4HV mentioned also.

Subject: [TCML] DRSSTC w/ long bursts and large Lpri
This is in reference to a comment Udo made recently on a DRSSTC thread, but I
didn’t want to clutter up the other thread with a reply OT to the main
discussion. Rather than sending this in private I thought the entire list may
benefit from seeing it.
[quote: Udo Lenz]
My idea of a "perfect DRSSTC" would be one using a large primary inductance,
which
could store a lot of energy for a given max primary current and a corresponding
long burst
time to charge it up. That would reduce stress on the transistors. Most of this
is
unexplored territory.

While it is largely unexplored there has been some recent very promising
attempts from our Russian friends, namely Zilipoper on 4HV. The full thread can
be found here: http://4hv.org/e107_plugins/forum/forum_viewtopic.php?160457
Video links of the coil in operation: http://www.youtube.com/watch?v=Obt3yRiuvEs
It seems that this kind of approach requires a MMC similar to that of the
classic SGTC, where extremely high voltage tolerance is required. The designer
of this coil has been blowing MMC caps with almost every run.
