Then, the tank circuits will be exicted by the natural magnetic Schumann resonance, but feed one output to the other for some additon of signals and feedback, the output might just go through the roof !!

I hope, more than anything, that this works, as does GK, and the rest.  What I find astounding, is that you have reached in three weeks, the same conclusion I had reached over many, many months in my Theory and experiment thread.  If you never have read my thread in those three weeks, that would actually be even more of a confirmation, since we have come up with almost the exact theory of operation.  But I give you Kudos and compliments, for in the "how to implement" you have done a marvelous job.  (If and when it works!  LOL) 

Similarities in our thinking:
1.  7.3 Hz (though I have in researched different math, as to how to have that as a "beat" frequency.  If this does not work, you may want to read the math on my thread, and try it with a 14.6 Hz difference to obtain the 7.3.
2.  The use and tapping into "standing waves".
3.  The use of Sine waves
4.  The "audio" component
5.  The "tuned loop circuit", which is where I was at last opportunity for research.
6.  The "cutting" of the collector to "resonance" to "tune" it.

I take no credit for your theory, simply amazed someone else came to near identical thinking.  It gives me great hope that this may actually work.  I do hope that GK will wind a special coil to the specs that you have given, to test this with.  We have high hopes. 

I know that some see the SM TPU working "differently" then you have laid out here, or I, in my thread laid out, but no matter what, it will be a grand experiment!   

@ GK
"Remember the KILL switch!  LOL     Good luck my friend!

High regards,

I found these in my bins.

Propagation delay of 100ns = 10 Mhz pulse, parallel loading.

Found one of these too:

And gobs of motor driver ICs from 40 amp motors down to miniature camera motors.

Just got curious about my dark inventory.

Got the 2 signal gens done and running. They needed bipolar supply. I have a +12v only. I look in my dark inventory and find 7660's. Amazing little bugger. Max is +10v. So I put a 7808 in place then the 7660 and viola. +-8v. Now have bipolar for xr2206 gens. Beautiful sine waves. xr2206 run very stable. Freq adj pots cranky. I could put the dac7541ajp's in to give 12 bit control. Hardwire the numbers I need, hehe. Fits the 12v operation.

Am jumping on the ad826 class A amps. Need dual supply here too. Will use previous +-8volt. 2 amps on 1 chip. I'll put the better channel separation in later using a 2nd 78L05 setup.

--giantkiller. Lots of analog here.

btentzer thanks for the heads up on your ideas too we must be heading the right way everything else has been tried there is not much left .. oh only triangle waves. LOL

GK your doing a great job on those boards. The class A amps are very greedy on the juice make sure use heat sink and the temp sense diodes must be done you cant skip that otherwise they turn into a molton blob on your desk. If you get stuck you might have to run the sig gens and amps off 2  little 12 volts yuasa batteries back to back to give you the dual supply and enough amps for the class A amps. It might seem an overkill but it has to be better to drive this with ease rather then risking any distortion and ruining the tests. You can of course test these amps on speakers first i bet they sound fantasic! DC to VHF

When SM started using tubes he would have had access to a good 2 or 3 watts of clean audio per channel so it makes sense. 

In fact if you wanted to "play" you could jut try using the sig gens and just see if you can spot anything nice with clean sine waves.  However you might also need to make a GK5 bigger and better to put control  in the center as SM suggests but whatever you wont see anything decent without ferrite baluns and magnets.
