I find the kick

rtl8186,  very nice work!  It's refreshing to see someone trying this with a tube as Mannix has been saying for so long. 
   Note to self:  Find that old box of tubes

@ all (not rtl)

Think of ..just for now, 2 perfect amplifiers who's ins and outs ( almost)  cancel each other via the rings windings and their relative position.

Achieving  this balance will require NO feedback (except for the coils) , wide band response , and be capable of high voltage operation so that later, when the spikes occur , (later)they don't just blow the components.

Get this balance ..now introduce a third amplifier, also in balance with the other two. You would have to rebuild everything again using what you learned from the first phase. You will have created a receiver of some different kind

3 perfect musical instruments all in the same circular  space ..will they resolve pi?

I dont mean to make it sound simple ..it surely is not

In fact there are some pretty smart guys here that are not even smart enough to use the correct devices. Which the actual inventor pointed you towards.

But first wake up!

Mannix ,thanks for idea I will think

I'm no expert in vacuum tubes, but I think excessive heat will prematurely damage them or you can have a fire hazard from heated wood that gives off combustible gases.

Yes you are absolutely right, but it is experimental installation and I include it no more than on 5-10min.

what DC signal magnitude do you have?

about 30mV

I suggest inserting very small capacitance at the terminals of the operating coils to change the frequency slightly and see what happens, you might hit on some resonant frequency that produces a higher DC voltage on the output.


rtl8186,   you might want to change the way you connect to the coils to try another idea.   Use the collector coils instead of the spiral coils,  and the spiral coils as the OUTPUT.   There seems to be some confusion about which is the COLLECTOR and which is the CONTROL coil.   If you do that, you won't have enough capacitance anymore, so you might want to insert a capacitor to resonate with.

Оk.I try it.

You know, it is very similar to the idea of a long garden hose.
Picture a hose with water in it.
If you pick up one end and move along the length of the hose you will
move the water constantly along in the direction you are moving.
You could also squeeze the hose in the direction to move the water
along as well.
And you could do both to control the movement of the water more
precisely.
You can think of the movement of water as the movement of
electrons through the collector coils.

Copper is diamagnetic!!!!!!!!!

From wiki

In 1778 S. J. Bergman was the first individual to observe that bismuth and antimony were repelled by magnetic fields.

from  the archives of Lester J. Hendershot :....facts:1.a magnetic field possessess a resonant frequency  2.the field can be put in a state of resonance by utilizing pulsed direct current  (page 26)
