  1. Input capacitor (2.2µF) blocks DC.
  2. 56kΩ resistor from input to ground sets input impedance.
  3. Signal enters pin 2 (Left IN) / pin 17 (Right IN).
  4. Internal differential amplifier and voltage gain stages.
  5. Output appears at pin 4 (Left OUT) / pin 15 (Right OUT).

Gain Control: Resistors in the feedback loop determine the amplification factor. 3. Output Stage & Zobel Network stk413-430 circuit diagram
