Maxim, can you post the whole schematic of the symmetrical amp?
Not sure if there is anything to gain from this symmetry, except visually pleasing schematic,
but won't know if I don't try...

Tomorrow I will only be able to throw off the material of the symmetrical version with the drawing of the Board. I prefer other schemes, also cascading.From a monster and another with OE in cascade.
Утром скину ,по московскому времени

Maxim, how about amp from the first image from post #176? The symmetrical one.
Can you post full schematic?

The scheme is not mine ,honestly copied
Protective diodes must be installed.As done by Ageev .

Symmetrical Wiederhold amp
Did the sim in LTSpice.
Doesn't look like it's doing better than asymmetrical version.
Slightly worse, at least from the Thd point of view.

pcb
Hi Stanislav!
excellent design,
Do you sell pcb for this amp?
Maybe you could share pcb printout for iron transfer?

Your model is not yet complete.Look at the Ageev amendment. OU take LM318 /LF357
На деле с моделью работать и работать
Symmetrical version of the model. I like.

My purpose was to compare symmetrical part, not the ouput. That's why i kept everything else the same.
I understand. I made a complete model for the illustration. By the way, why don't you use a buffer stage before the field-effect transistors?
These are Lateral fets (2SK1058/2SJ162 or Exicon equivalents), they don't need drivers.

Is this inverting amp?
So I guess you think that 'symmetrical' approach has advantages in these amps?
Can you explain why is it better?
