a little more on topic
have you tryied running your primary and base winds in the same direction as your secondary turns
many months ago i notice i got better results with less secondary turns and ma's draw
what i had was 3 layers of 5 turns each for primary and base.. but with only 2-3 turns secondary i could charge a cap real fast to 80-90 volts with around 100 ma's
but it was a 4.56'' coil
i could try to make another one and see if i can get the amp draw down to a nice setting..

Yes Yes topic Good .

i can't picture what you are saying , please explain more.

But the idea of the gate coil is for no direct coupling , its so hard to explain
is like tying to make a bad transformer , since there is no coupling secondary are under no direct coupling that way you can have many secondary loaded and maintain the push of the pulse.

Anyway quite educative , there is so much potential , i barely sleep at all .

It doesn't behave like any transformer i know.

on my jt that runs below the 1 ma mark it is weird
when i get to 0.54 ma's the secondary wires go negative ..(both wires) and light the leds
8 leds to half or better brightness..
i just thought that was something neat..
you guys probably already know this stuff.. but i am still learning since i got this scope..
