Audio Transformer creates isolation between the output speakers or audio circuitry with the transformer’s input side amplifier system. The primary and secondary winding turns ratio fixed to 1:1. Due to this, the transformer does not alter the voltage or current level.

Audio Frequency (AF) Transformers work at frequencies between about 20Hz to 20kHz and are used in audio amplifier circuits, they were essential in valve (tube) designs for matching the high impedance outputs of theses amplifiers to low impedance loudspeakers, but transistor amplifiers have much less need for output transformers.

Audio transformers are ideal for balancing amplifiers and loads together that have different input/output impedances in order to achieve maximum power transfer. For example, a typical loudspeaker impedance ranges from 4 to 16 ohms whereas the impedance of a transistor amplifiers output stage can be several hundred ohms.

Audio transformers must utilize both high-permeability cores and the largest practical number of coil turns to create high primary inductance. Coil inductance increases as the square of the number of turns and in direct proportion to the permeability of the core and can be approximated using the formula: L = 3.2 N28 ì A / 10 R

OUTPUT AUDIO TRANSFORMER DESIGN The output transformer in a single-ended tube amplifier is the device which matches the high-output impedance of the tube to the low input impedance of the speaker load (4, 8 or 16 Ohm). To design an output transformer, it is necessary to determine the output power according to the tubess characteristics,
