Stubblefield coils (bifilar) and speculations

@ Gary:

I believe the output from the flash circuit is ac, around 300-400 volts and I have no idea about the freq. but I suspect it is pretty high.  Last night, I lit 300 LEDs using a single AA battery and my modified Fuji circuit.  I would be careful using this type of circuit on a few leds, I tried at first, just 100 (100 per Christmas light string) and it was way too bright so I only had it connected for maybe 2 seconds.  I then did 200 and it looked like they were going to survive so last night I tried 300.  They lit up nicely.  I tried testing the output from this circuit but my meters won't handle it, and no one on our JT topic was able to measure it.

So could we say that is circuit has very similar results to the Dr. Stiffler circuit?
Try repeating all the tests he used and if you get the same results as he did then it may be.
Have you tried connecting just one lead from the unit up to those LED's?

I remember reading that the output was around 300 V  that is why I thought that it might  burn up my LED christmas tree lights ........regular lights would be more likely to work with overvoltage .

Yes, for this particular Fuji circuit (there are several variations) it is supposed to be about 300, 350, or 400 volts.  I have read all of the above at one time or another.  I have no way to test except by the load it powers. (300 leds and counting, grin)  I have fried leds before and it is not pretty. (smells too)
