@Nyemi,
Wat do you mean with:
Primary 2 lines, winding!
Secondary 4 lines, winding! (just pair, no 3-5 lines, Not abandoned the line!)
Wat you want is secondairy 0,2mm = 4x 0,05mm twisted pair ?
And primairy 2 lines, just two wires next to each other ?
I try to ingreas the schematic and make it usefull for model engines, but even with small power consumtion (<25mJ) some HV-parts will be hot.
