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.

Line Output. Typically, audio transformer is driven by an amplifier and loaded by several thousand pF cable capacitance and high input impedance of line receiver. Therefore, a line output transformer should have low output impedance which remains low at high frequencies. This requires both low resistance windings and very low leakage inductance. 5.

1 Audio Transformer Basics Since the birth of audio electronics, the audio transformer has played an important role. When compared to modern miniaturized electronics, a transformer seems large, heavy, and expensive but it continues to …
Audio Transformer, its Types and Impedance Ratio
https://circuitdigest.com/tutorial/audio-transformer
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. It does only create isolation between the Input amplifiers with the output speaker system.

The output transformer is the heart of a valve amplifier. The right pic shows a stereo Leak amplifier. The two output trannys are rotated 90deg to the power mains tranny to avoid picking up induced hum from the mains tranny external magnetic field. Output trannys contribute most of the distortion in a valve amp and have a limited bandwidth.

not sure about air gap, there is SOME info on the web. the primary turns is a simplification of the classic transformer equation, viz. B= (1.10 ^8 x volts) / 4.44 x Frequency x Area x turns. where b = ac flux, I have used 8000 here. frequency = 20 hz. Core area = 450 x root power out in mm squared.
