A Push Pull Output Transformer is comprise of three windings that is wrapped around a magnetic core.  In a push-pull amplifier the power is connected to the center-tap of the transformer while the tube is connected to the lower and upper end of the center-tapped primary.  What this does is allow the tubes to work on alternate cycles of the input waveform.

For a  push pull transformer to work it  requires at least  two tubes to operate.  Push pull output transformer can have a "Parallel Push-Pull " operation, which allows  more connected in parallel with each side, which results in an amp with four, six and eight output tubes for higher power amps.  A push-pull output transformer can be a class A or class AB.  Class A is where current  flows in both tubes for the entire input cycle, but in opposite directions in the output transformer. This allows the sum in-phase in the secondary winding and the DC offset bias current cancels out which prevents core saturation.  This also allow use of smaller, ungapped cores. Most designs are biased class AB which offers better efficiency and power output with minimal crossover distortion but not necessarily the best tone. These work by allowing current  to alternately flow in both halves, but less than a full cycle in each, or class B, where current flows only half the time in each tube.

Advantages of Push Pull Output Transformers

  • There is little unbalanced DC current in the output transformer if the tubes are matched and the output stage is balanced.

  • Push pull output transformers are in many cases cheaper because the current flows in opposite directions to each tube, allowing a smaller transformer with less iron.

  • Even order harmonics and distortion generated in the output stage are canceled out.

  • Power supply hum is canceled out, which mean less filtering of the power supply.

  • One possible disadvantage in class AB operations is that the DC supply current changes dramatically between off and full signal. This requires heavier filtering to prevent supply sag, unless that is what you are looking for in guitar amplification.
