Resistor uses the1/2W high quality metal film resistor. The capacitor uses the imported CBB capacitor. All the transistors must be matched strictly. Matching error must be controlled in 3％. L uses the 1.0mm enameled wire with 10 turns tightly wound on 12mm frame. You can adjust the quiescent currentaround 100mA afterpower amplifier tube welding correctly andcheck the matching transistor error if midpoint potential of the circuit can not be controlled under 30mV.
