Thank you for the nice words. You should know that you are in my prays
and thoughts and I hope you get better soon. I was glad to see you post
here at the forum. It has been so long since I heard from you.

I still have the JT you sent me and has run many tests on the circuit. I have
discovered some new things based on that testing. I came very close to OU
with my new figure 8 cores. I was able to lit up a 230 VAC 25 Watt lamp
with only 29 Watt input. The 4 Watt loss was mainly in my bias circuit since my
coils did run cool and the transistors did not heat up too much. My new figure
8 core is still running but I have not solved the bias heating issue yet. Anyway,
it is good to see that you still can find the strength to post here. I miss you
being around here.

I have attached my newest figure 8 circuit. You can get very high output
voltages from this circuit. And the circuit does NOT behave like a normal
transformer where you get a output voltage based on the input to
output windings ratio. If someone build this circuit, please be careful
not touching the circuit when you run it a high power because it can
harm you.

Sorry to be a little off topic, Bill.

Alex, (Groundloop).

Thanks to Gadgetmalls & resonanceman for advise. I dont have any caps with me now so have to wait till monday to get it. Nervous and eager to c the result!!

sorry to ask this, but where i supposed to connect my caps?

Those 12V and 0.3mA come from 27 units of EB connect in series with adding dilute salt solution So currently finding ways to increase those ampere. Any suggestion instead of using salt?

Thanks

KB here is a schematic of the circuit

Any cap you add should help a little........although  a good sized cap  is best

Alex:

Nothing you guys, the experimenters, can post here will ever be off topic.  So please, don't ever be concerned with that.  It is all related anyway.
