1) (vladi1,vladi3,vladi4,vladi5,vladi6,tcconv1,tcconv2).jpg
First version of spark gap TC: Xformer: 2x6kV 50mA NST in series, Capacitor: 24x25nF 10kV polypropylene film foil series/parallel for 16.6nF 60kV total, single spark gap, pfc corrected. 23" max spark length. Second version will have a flat spiral copper tube primary and 12kV 200mA NST multiple SG.
2) (mosfet1,mosfet2,mosfet3,mosfet4,mosfet5,mosfet6,mosfet8,mosfet9,mosfet10).jpg
Self tuning resonant mosfet TC, Half bridge configuration 4xIRF460 Mosfet, 64x3.3nF 2kV MKP capacitor for resonance, 200KHz c.a working frequency, modulation selectable half or full mains wave envelope, forced air cooling.
3) (mosfeta1,mosfeta2,mosfeta3,mosfeta4,mosfeta5).jpg
A smallest version (see ruler) of mosfet TC. The pluggable resonator makes it portable to experiment at a friend's home. Envelope only full wave rectified mains.
4) (ubjt,ubjt2).jpg
Micro version (see ruler) Clapp oscillator with one hi voltage bipolar transistor, the input is dimmed by a triac and the envelope is half or full rectified mains wave. 4MHz frequency operating.
5) (utube,utube2).jpg
Micro version (see ruler) of tube TC 600KHz operating freq. envelope: full or half rectified mains wave. Tube 1xPL504.
6) (tctube1,tctube2,tctube3).jpg
3x807 (now 3xPE0640N) VTTC. 6" half (at max plate current)wave beautiful brush discharge.
7) (mvc003f,arostube1,valvola).jpg
First model of single EL519 VTTC, Second version is: 10" spark with single EL519 tube.
8) (813,tescomp,mvc044f, and now, 813_primary and 813_secondary).jpg
components to make 2x813 VTTC (the exact text is the one just posted)
9) (mvc019f,mvc045f,sov1b,4c100,GU81_2,5c110_1,gk71-5,4c100&813).jpg
Tube for build VTTC similar to John Freau type
