Ok,
After having a look at the schematic of JNL (!) i must say that there are some differences between the schematics of Stan and JNL.
The most important difference is that the secondairy circuit of JNL has a shared ground with the primairy circuit.
Stan wrote vey clear that he didnt wanted a shared ground.
How far this matters, i cannot answer yet.
Other difference are the resistor and the insulated innertube.
I also see what others already mentioned before that JNL has drawn the bifcoil wires not as they should be.
I cannot confirm that the way JNL shows his wires, that that can work. I got my step-up charging with a reversed wiring of one of the 2 coils.
I am SURE about the fact that the only way to get real HV with low amps at yr wfc is by using an FULLY insulated innertube (maybe a fully insulated outertube, with a non insulated innertube will work as well...
)
I also remember an interview with a person who was doing a replication of Stan with an Insulated innertube. He said that he didnt care anymore for the gasoutput of his device. He found out that this setup was producing! losts of current! It produced more power then consumed...
Now, that sounds interesting, is it...
