What is the main advantage obtained by using two triodes in push-pull in a Class a audio frequency amplifier?

🔍 Key Concepts

• Push-pull amplifier operation and how two devices work together • Difference between power output and distortion characteristics • What happens to even-order harmonics in a balanced push-pull circuit

💭 Think About

• When you mirror two identical triodes in push-pull, what happens to signals that are equal and opposite in each half? • In a push-pull stage, how are the fundamental signal and the even harmonics treated differently? • Which of the listed effects (power, distortion, DC conditions) is the characteristic textbook reason designers choose push-pull for audio?

✅ Before You Answer

• Verify how even-order harmonic distortion behaves in a perfectly balanced push-pull stage • Consider whether increased power output is a guaranteed result of using push-pull, or just a possible design choice • Check if push-pull operation naturally affects DC flux/saturation in transformers and the need for a cathode bypass capacitor

Question 1 of 27070

What is the main advantage obtained by using two triodes in push-pull in a Class a audio frequency amplifier?

Increased power output

Cancellation of even harmonic distortion in the output

Elimination of DC saturation, elimination of cathode by-pass capacitor

All of the above
