This is vero schematic
I have 2 questions
1) DA 1.1 Whether it is an obligatory part of the circuit or just closes the second half of the chip
2) DA 2.2 The voltage divider is perfectly capable of operating without a chip, why is it here?
JFET КП303А, D7,C12,R34,R42,LED,D11 Must be removed if you want true bypass.
