Just for clarity.
This simplified version free,(4 layers pcb), using Jensen JT-11P-1 Line Input Transformer.
I believe that for a lover of good music (I have listened well the proto) can be the maximum you could want. (in my experience music).

As I understand, he has just explained the simplified version.
Input transformer + mosfet output stage = F6
Input transformer + mosfet output stage = F6
Hi, The power is subject only to power devices, I chose up to 400w (3R) 5 MHz, a pair on each side. for the amatorial version. also it is a complete amp, need only power DC and +/- 20V to 40V unreg.
for the diagram is better to wait.
ok,
but it seems also final super-version has transformers.
So, which type has flat band from 20Hz to 150MHz?

Sure, I described the simplified version (compared to the complicated version)
input transformer is used right input. (between the transformer and the MOSFET, there is the sea compared to f6).
The project started with the complex version. amatorial version is just my idea..without business.

Transformer is not used as the gate driver for output stage?
You have the sea of components for that purpose?
And you have applied the patent for this sea of components, not for the transformer and not for the output stage?

if you say any amp with input transformer and mosfets are equal to F6, that is close to offending Nelson Pass
I think we need more/better details before jumping to any conclusions
if it puts out 400watt, and is freely available ... I'm sure a few members here would like to build it
With your AP2 circuit, Will it deliver a natural sound that brings music to life as claimed by tube fanatics?
You are right.
Could also resemble one of Susan Parkers designs...
Or anything else "similar"...
So you are right about needing more information to see what the revolution actually in it is...
Transformer is not used as the gate driver for output stage? No
You have the sea of components For That purpose? (for.. linearity compensation in DC, cross point detector, stabilization for high bandwidth, auto offset, differential offset control, auto bias, all protections.
this is already present in the amateur version.
what is patentable, are the way how do I get all of this.
I tried to have the natural behavior, such as when a string vibrates.
the vibrating string is free to move with motion synchronous / asynchronous. this is all.
I chose the class analog for obvious reasons but looking at how to remove the "ballast" and unnecessary dissipation.
then we got (in the path of the signal) extreme simplicity. and complexity in the control of the amplifier.
The amplifier is stable as a rock, no drift, no noise, no changes even after 6 hours at 15-16 amperes output,with acceptable thermal dissipation, (also considered the extremely high slew rate).
I hope you can make a brass trumpet sounds like a brass trumpet not as in elephant and I'll be the one to appreciate the value of your work.
Hello AP2 , when you initially mentioned the amp seemed to be ''designed by transients'', it had me thinking about derivative dv/dt function serving a purpose in the design. In controlling the output devices, if you have been freed by the ball and chain of DC bias, are we looking at a large emphasis of derivative and/or integral functions..? From what you are saying it sounds like standard NFB ( proportional control) is much reduced playing only a minor role in providing local FB. Interested in seeing this soon.
AP2 and tinitus. A sentence simultaneously containing digital amp and Mr. Pass is extremely rare. Is it possible that AP2 has "digitalized" the F6 Class A amp of Mr. Pass? Maybe AP2 means to blend the attributes of Class A and Class D to make a Class A/D amp.
Best regards
don't know, but sounds strange to call it classAB if it puts out 400watt in 3ohm with just two output transisters
(maybe it would be more like pure classB ?)
as I understand it, it originates from the already existing commercial classAB
and the very complicated input/driver stage is being replaced by small input trafo, to make it more DIY friendly
sure, Nelson does that too, with a probably completely different classA design
but I don't see why that automaticly eliminates any other use of input trafo
many tube amps have used input trafo long before any other
Nelson's F6 is most likely very different
