Here is a 6 Watt Amplifier.
EXAPP is it called.
Uses EXICON Lateral MOSFET. Class A Push-Pull.
Will draw 18+18 Watt.
Distortion is low.
Bandwidth is okay.

Lineup, I`ve never seen a single thing you made, what is the purpose of opening these threads and endless simulations?
I have actually made one headphone amplifier.
It sounded great.
I even posted the schematic of it here at diyaudio many years ago.
But you are correct.
I just simulate.
Because it is fun - and I want to share my work.
So others can build it.
As a matter of fact I have another amplifier on the way ...
Do you @bogdan_borko want to build?
You are interested as you posted here.
Good Luck 🙂

It's (hopefully) a free world, if you don't like it don't read it, what's the problem?

If there is anyone who has questions of this amplifier
I could provide more information.
It is a good amplifier.

Here is the data of EXAPP amplifier.
THD is 0.00055% at 1 Watt 8 Ohm.
Max output is like 6.5 Watt at 8 Ohm
See image one: The amp with currents at idle
See image two: Fourier Analysis at 8 Ohm
See image three: AC Analysis

You know you can buy ECX10N20 and ECX10P20 from here:

Here is the data of EXAPP amplifier.
Can you work the circuit a bit to lower the 5th and 7th harmonic?
I’ve read many times to keep the 5th as low as possible.
Thanks

I know.
Simulation does not accurately reflect what may come in real life.
I don't know how much I have had to say this.
Now I don't build.
I leave this to others.
Thanks for pointing this out.

I do not know a way to do this.
I simply must take the result as it is now.
The amplifier is tweaked alright.

Promising - lets see the final measurements of the real ting. I suppose you have the means?
//
I do not have possibility to build amplifiers.
My little room has no space for building electronics.
However I have a function generator.
Also have a package with resistors. And solder iron.
I leave it to others to build and measure.
The Gerber files are on the way. For making PCB.
Should be posted here soon.
