even 0.1 is looking terrible - 11 cycles, who uses this? 0.03 is
just for crazyest crazy imo % ) i`m not considering ss gaps here : )
but even if i set k=0.1 and load secondary (after full transfer) with
500 kOhm, about 8kv (from initial 20kv) will show up in the primary. of
coz i don`t have a model of real sg, so maybe all of this is wrong.

thnx, i`ll look at this. and probably ask more then : )

correct me if i`m wrong, but aren`t the "russians" studied influence
of VRT in case when breakdown starts before full marx erection? and
they just don`t need/want to get all energy in the system before start
of breakdown?
when you use breakpoint on toroid, you get the same situation, but who
forces "me" to use it? why "i" can`t wait when most of the bang happily
climbs on the top, and then suddently jump from there in violent
capacitive discharge? : ) i`m kinda dreamer, you know : D

yeah, now you can build a factory and start to stamp the coils with
+-0.1" in output spark length tolerance. decorative coils in the
kitchen, wc, your car, on your work, and even on your grandma lawn : )

haven`t you measured Q primary with "gap" yet? % )

you`re right on both cases, so be prepared to some number of
questions. next week probably : )
