I tried myself to get a DRSSTC beginings story. I dont know if it is very acurate, I am on internet only since 1999-2000. Something like that: 2000-2001: Aron and Justin (HVguys): self tuning SSTC (the site is down) 2001 feb: Mazzilli Vladimiro: mini double resonant interupted SSTC (primary resonant cap and primary feedback) http://www.pupman.com/current/vladi2/mosfet.pdf 2001 dec: Carl Willis interupted fixed frequency SSTC: http://www.angelfire.com/electronic/cwillis/fetcoil2.html 2002: Jimmy Hynes DRSSTC using a VCO oscillator: http://www.capturedlightning.org/hot-streamer/chunkyboy86/index.htm 2004 mar: Steve Ward ISSTC (self tuning but not resonant primary tank) http://www.stevehv.4hv.org/ISSTC.htm 2005 Steve Ward- the first DRSSTC as we know it (resonant primary tank and self tuning) http://www.stevehv.4hv.org/DRSSTC1.htm > > -------------------------------------------- On Fri, 12/27/13, Antonio Queiroz <acmdequeiroz@xxxxxxxxx> wrote: Subject: [TCML] Looking for the origin of the DRSSTC in the archives To: tesla@xxxxxxxxxx Date: Friday, December 27, 2013, 4:20 AM Hello: I was looking at the list archives at www.pupman.com trying to locate the first reference to the "drsstc" and other variations of the Tesla coil using solid-state drivers, that probably appeared between 2001 and 2003. But I could find only scattered posts, apparently from incomplete threads. For example, this post is apparently not there (the title is a bit exaggeraged...): http://www.capturedlightning.org/hot-streamer/temp/Probably-The-Most-Important-TCML-Post-Ever.pdf Are the archives complete?
