Figure 21-2 is a common push-pull amplifier circuit; And the tube can work in the class of A1 or AB1. As invert tube V2 has no amplification effect, it can be seen as polar amplification. Feedback resistor R1 is separate from the cathode bias resistor, the feedback resistance is only 10Ω, the resistance is very low, so the feedback current of V1 tube is negligible. Inverter circuit adopts the way of Figure 20-6, it does not use the transistor but use pentode, for simplicity, the balance of output voltage of the inverting tube is seen as 1.
