The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.
yestreday a good friend of mine come to visit me and beeing a little bored we went down to the workshop to do something. Hmmmm - looking around we've spotet an old SSTC secondary that I've made 2 years back (no varsnish). Soo after thinking thoroly (for 3 seconds ) we've decided to build a smal RSGTC.
Power supply - ZVS + DC flyback Primary caps - 3x2.2nF 5kV !!! (yes 5kV russian caps - and they survived with no problem) primary - 9 turns hellical style power consumption - unknown - the 10A fuse on the secondary side of the transformer didn't blow Sparks - around 22sm into the air - 26 to grounded object (measured by a friend of mine ) The pics are taken in a day light soo they don't do justice to the lenght. Also the pics of the whole setup - it is a little different in the moment (added the 3rd cap)
Any suggestions about improving things are wellcome (this is my first SGTC and no experience what so ever )
Still thinking shoud I build it nicely and permenently I am shure that with a little varnish and better tuning this thing can push more sparks. Cheers :)
first - sorry for the double posting but I have a big progress
Sooo this night we got together with my friend and started thinkering it. First we've connected the caps as they shoud be - this short wires, *insulated* the secondary with a duck tape (I know I know - but it was already badly damaged sooo I didn't care. Then we've started playing with the coupling and theeeen it turned out that I had too little primary turns - sooo we've added 4 more and started tunning. Suddenly this thing went nuts - around 30sm streamers and sparks comming from everywhere
Here some pics . A little bit high coupling at the last one.

Wow, nice! And this is your first sgtc? NICE!
Hehe. I was planning on making a sgtc with my zvs, but seeing how my zvs kills flybacks in a few seconds ever without the added abuse of a coil, i don't think i could with a regular small dc flyback. What i might do at some point is make another ac flyback with a few kv out, double the voltage, and then some hv caps that i have. It will be fun if it works, but i might need a charging reactor, which i have nothing to use. Anyway... I dont think i have ever seen a tesla using a zvs driver, voltage doubler, AND homemade ac flyback... And rsg at the same time :O
