I agree and your point is well taken.

The reason not much information was not given on this project was because at
the time, there was a commercial interest involved and this
circuit was being produced as part of a commercial effort to produce an
affordable solid state tweeter system for the audio market.  However, at
this time (as i mentioned on the 4hv group), i have decided not to pursue
this venture much further.  Therefore, I will be posting all the stuff on my
website this weekend as time allows.

This is the same reason I am not discussing or posting any information or
news regarding my Advanced SSTC controller as it is currently titled as I
also have commercial interests involved with this (not so much as an SSTC)
This system is already working quite well (although not without problems)
and I am currently in talks with selling a number of units to a local
university's plasma physics department.  (This unit can drive a SSTC with
arbitrary waveforms (RF envelopes, burst modes, pulse modes, sine wave,
triangle wave, or whatever)

Here is an outdated photo of this ASSTC unit from last winter.
