A feedback loop runs from the speaker output back to the input differential pair to set the gain and linearize the frequency response. A "Zobel Network" (Resistor + Capacitor in series) is placed across the output terminals to stabilize the amp against reactive speaker loads. 4. Troubleshooting Guide (Circuit Level) If you are diagnosing a faulty RX-4000, check these specific areas:
Signal from Pot -> Differential Input Pair (Transistors) -> Voltage Amplifier Transistor -> Current Source
