This project is my best product

Excellent, I'm starting designing a PCB right away .

wazzat in the middle, some sort of folded cascode?

and where do your arrows go to?

it is unusual, can't say I've seen anything quite the same overall.

signed,

_-_-greatly confused

 

[Stee]

in the middle there is a diamond buffer as driver for inverting VAS
so the arrows goes in supply voltage +/- 27V

Waly it's possible see the layout of PCB?

.... This is irony, Stee - You can't expect anyone to understand your "design" from incomplete and unconnected "cut and paste" circuit elements such as your OP.
For credibility, you need to complete the electronic design and demonstrate that it works acceptably before anyone else can verify or rework it.

No labels makes it hard to discuss.

The transistors in the *center* of the drawing?
The top takes a 100R resistor??

 

[Stee]

see now the complete information

this design is a chain of diamonds:

an input buffer
then the NFB resistors
then inverting driver and VAS with load resistor
then a One-Wire EF Output Stage

you can edit picture to improve

BLOCKS VIEW

FEEDBACK works better with resistors
if you have low "weight" of correction
then feel more accuracy in middle-high tones

NEW STYLE

of function schematic 😕
