Self Running Micro TPU, with closed loop.

PNP symbol is PNP.  Cool.  Thanks! 

...The coils are the same for the Bedini SSG project at yahoo. They are 23 and 26 awg. Bifilar and about 1800 turns.

I assume that the thinner, 26 AWG, wire is the one that is attached to the base of the PNP?

That should be my last question... oh, wait, are the wires twisted together before wound on the bolt?

There, that should be my last question.

@Groundloop
you are correct. The top is the positive (big plate). NPN will not work but I have not tried it with battery polarity inverted.

@Rosphere
the thinner wire is at the base of the transistor. The coil is air core wound on a spool.

@all
Once you get the circuit built you will have to play with it until you find the correct spot for the base resistor (not used on my circuit) to trigger the transistor and keep it oscilating.

Fausto.

Try to replace the capacitors with non electrolytic ones. Polypropylene or similar, and see if it runs then.
