Transformer Coupled Audio Power Amplifier: Untuned large signal amplifier (power amplifier) of class AB and B type invariably use transformer coupled stages while those of class A type also generally use transformer coupled stage. RC coupled stages are not used because the quiescent current flawing through the load resistor results in large wastage of dc …

Instead of coupling capacitor like in RC coupled amplifier, a transformer is used for coupling any two stages, in the transformer coupled amplifier circuit. The figure below shows the circuit diagram of transformer coupled amplifier. The potential divider network R 1 and R 2 and the resistor R e together form the biasing and stabilization network.

On the other hand, transformers as coupling devices add about 80 Ohms across the whole audio band, because this is the sum of their windings DC resistances. Thus, in some environments where the lowest possible output impedance is needed, a direct or capacitors coupling can be preferred.

None the less, a transformer coupled design is both tougher to design and more likely to suffer bandwidth related distortions than a capacitor or direct coupled design. Isolation can be improved with a transformer but the capacitance must be kept down to a bare minimum.

The above diagram shows the circuit diagram of the transformer-coupled amplifier. In the circuit diagram, one stage output is connected as an input to the second stage amplifier through a coupling transformer. In the RC coupling amplifier, cascading of the first & second stage amplifier can be done through a coupling capacitor.

Transformer coupling at the output of a preamplifier gives a flatter impedance output over the audio frequency band. It seems to be a myth from old tube amplifiers that transformers result in rolloff or lack of detail, good ones don't.
