6L6A class tube push-pull amplifier

When the load impedance of the push-pull amplifier stage is 5kΩ, the 6L6 amplifier tube is in the Class A push-pull state, the plate voltage is 280V, the plate current changes from zero signal to full signal to 120~140mA, and the output power is 15W. If the 6L6 amplifier tube is used for Class AB push-pull work, the plate voltage can be higher. When the plate voltage is 360V, the plate current I changes from zero signal to full signal to 85~135mA, and the output power can reach 30W.
