The special design of the output transformer then enables the correct reconstruction of the amplified signal at the output terminals. The advantage of the push-pull system lies in its ability to produce greater output power than is obtainable from a single-ended design using the same type of valve.This advantage is determined by the greater efficiency of the push-pull system, and means lower heat dissipation for any given output power. The disadvantage of push-pull stages is that, relying on the amplification of two separate half-wave signals by two separate amplifying devices, they must be particularly well engineered in order not to encounter significant distortion
