Bill you would not want to put them in series.  They would have a very hard time starting up.  These sorts of things should be connected in parallel.

Thanks Mark.  So, if connected in parallel then the 3 oscillations do not have to in sync?  I ran into this a few years ago when putting 2 Fuji JT circuits together in parallel.  On the am radio, you could hear 2 different oscillations going on...one was climbing up while the other was falling...and so on.  I guess I did not have synced resonance which is why I did not achieve overunity like those QEG folks, ha ha.

No they don't need to sync.  Ideally, they would be offset 1/3 of a cycle from each other.  Since they are not, a capacitor can smooth things out. 

You did not have enough people humming properly to achieve resonance.  For just $15,000 donations for my wife and I to fly to Hawaii first class I can advise you on how to get better resonance.

Works, the feedback winding will run both transistors.
