This is obvious but I don't think we've understood each other about the word amplifier.
I meant an amplifier in the sense of a power amplifier, e.g. for a music.

Wesley's Answer:
It is  the same for every  amplifier-  the same rules apply.
Read  Wikipedia.

Why do you need a power amplifier? Each tesla coil is your amplifier and transmitter. As a last resort, you can use the music version of the tesla coil!

Cytat z Wiki
Most modern audio amplifiers have a flat frequency response as shown above over the whole audio range of frequencies from 20 Hz to 20 kHz. This range of frequencies, for an audio amplifier is called its Bandwidth, (BW) and is primarily determined by the frequency response of the circuit.

Wlasnie sprawdzilem jak wyglada uzycie Wzmacaniacza audio Blaupunkt  PCA2120 2x120W 1x300W.
Podlaczylem generator sygnalow i uzylem wylacznie pozytywnej czesci pulsu sinusoidalnego niebedac pewnym czy
to cos dziala na sygnal przemienny czy tez tylko staly w postaci impulsow ( az tyle to nie wiem a szkoda mi tego wzmacniacza, moze w
nastepnym aucie mi pogra jeszcze )
Na wyjsciu oscyloskop pokazywal sygnal sinusoidalny a wiec to by moglo calkiem niezle dzialac przy 13-14volt i jakies 10 amper.
Niestety zgodnie z informacjami o wzmacniaczach audio wraz ze wzrostem czestotliwosci tracisz tzw GAIN. Jego mozliwosci wzmocnienia sygnalu znacznie  spadaja powyzej 120khz . A wiec wyciagajac wnioski moge spekulowac ze daloby sie zrobic Tesla coil na podobienstwo Slayer Exciter i kontrolowac czestotliwosc ale tylko na duzym lub bardzo duzym transformatorze ktory ma swoja czestotliwosc rezonansowa
w granicach 100khz i ponizej.
Wlasnie dlatego szukam mozliwosci podlaczenia generatora sygnalow do wzmacniacza ktory bedzie pracowac satysfakcjonujaco w przedziale czestotliwosci radiowych aby transformator Tesli nie byl duzy oraz latwy do zbudowania i szybkiej modyfikacji w razie potrzeby.
Dziekuje za pomysl i pozdrawiam

Luc,

Allow me to ask this:

- Will your power transmission work without the top load capacitors in place?

- If the top terminal is one plate of a capacitor, where or what is the second plate?

- How do capacitors work?

Okay poynt99

Both Tesla Coil top load capacitors are removed and circuit still delivers 7 watts through the single wire to Rx 50 feet away and even outside the concrete block building that Tx is located in.

The power transfer efficiency is not as good since I had to use a lower resonance point of 150kHz for stability compared to 230kHz originally demonstrated.
Without the top capacitance the ideal resonating frequency is much higher, difficult to tune and I fried a few mosfet's trying to get it.
So I had to settle with 150kHz. However, it still should be fine to prove the point that the circuit has not been using the top caps to complete the current path.
So how is it completing the current path?

Going back to single wire power transmission .
I apologize for messy drawing. Thinking about this experiment https://overunity.com/17735/wesleys-kapanadze-and-other-fe-discussion-forum/msg537420/#msg537420 i wondered if its equivalent to placing a capacitor at the bottom of tesla coil and
connecting earth end of a coil to one plate of  capacitor and single conductor to other, same for Tx and Rx . I did just that with random capacitors and its working like capacitor was
not there, makes no difference. I took no measurements just tried it.
So whats the point:
since this work should lead to power transfer via earth and so called interface - surface wave, i doubt that single wire ( metallic conductor )
will lead YOU anywhere close to your goal. Im not a skeptic and i did read about plans and ideas of using surface wave to send and receive signal between airplanes sensors and main computers on outer shell and wings (mam na mysli aluminiowe  poszycie samolotu ale nie wiem jak to nazwac po angielsku) in order to save money on wiring and weight of a plane itself and i totally agree it will work but for engineers with proper know how, understanding and state of the art equipment . So the wave exited by Tx bounces back and fort and gets utilized in Rx some 40 or 70feet apart might be easily mistaken by a surface wave and give you false assumptions.  Its just an opinion and i wonder what Wesley can say about my drawing.
Thank You

It is  absolutely lifting me up that I have so big Polish  participation in here.
And it is not because of Marie Skłodowska Curie
https://en.wikipedia.org/wiki/Marie_Curie

My wife is Psychologist  she was born in Poland  and she got one of the best level of education possible.
There is something unique about these folks.
Something that made them different among many nations around.
Fighting  for so many centuries with Russian Aggressor they developed  need of being better and better in everything.

Simple and short:
You put them at any place and any country,without knowledge of language, green card, and zero money  in the pocket
-dentist can become successful and wealthy construction guy in just 15-20 years from 15 dollars in his pocket  when he landed in Kennedy airport.
-surgeon will become  successful banker
-and microbiology student can become respected professor in famous  American university

Typically it was 6 to 10 years for most  of them to buy their first house in USA
Besides of Tadeusz Kosciuszko and Pulawski being heroes of American history.
https://en.wikipedia.org/wiki/Tadeusz_Ko%C5%9Bciuszko
https://en.wikipedia.org/wiki/Casimir_Pulaski
I could simply say that just because of skills of these folks fighting with Russian aggression 
their escape  to America  - America got its independence under their command .
Today _(Wednesday) is my holiday
And today I as an American express to you my Polish friends  my respect to everything you value.

Uniqueness of Polish Education System .
In 1950-2010 they had to learn approximately 300% more than average American in areas that have
been not so much included or just only "mentioned" in American school system
So their overall education  was very broad and not so much specific .
This was good and bad.
But becomes a precocious (exhibiting unique  qualities)  to/by any one who had to run for life from Poland  from
Russian oppression especially in  20tieth  century.
For these who don't know it was Poland who made possible  :
-fall of Berlin Wall
-freedom  of several countries from Russian/Soviet terror 
- fall of Soviet Union  starting from 1980 to 1991
https://www.britannica.com/biography/Lech-Walesa
So what do we need this information for?

Polish are quiet, peaceful pushers of everything around.
I'm pointing at enormous and very uncommon ability to adapt to any possible conditions of life.
This is their uniqueness
- Great educated nation of quality people.
-Poland as leading economy in EU (GDP ) looks like sweet beautiful clean, modern candy - she shines  with her beauty.
-Poland is not chap like some of other Eastern European countries but you'll get what you paying for.

And I happened to be very much oriented in all of the aspects of that part of the world.
I understand all of 27 Slavic languages,
I speak 3 of them fluently
And two of them absolutely perfect... well..only  after few days  of being there..
