turns = 33 x root of 2500 = 33x 50 = 1650 turns, 5 layers prim, sec, prim, sec, prim. 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.

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.
Audio Transformers - Learn About Electronics

In the 100V line speaker system, a transformer steps up the audio output signal voltage to 100V so that the output current for a given power is low. The resistance on long cables between the amplifier and loudspeakers will attenuate this low current signal much less than if the current were left at its normally high level.

I’ve been reading books & online, trying to learn more about transformers. I’d like to do some breadboard tests and build some circuits. I bought a Radio Shack audio output transformer, 273-1380. I believe it is 1000:8 ohms outside & 500:8 ohms center tapped. Is this picture a legitimate...
Valve Amps: Output transformers - Lenard Audio

Pi winding is commonly used in ferrite core trannys that transfer energy at very high frequencies, as seen in switch mode power supplies and Rf amplifiers. Pi winding is also the perfect method to construct an audio output tranny. Pi winding output trannys are not known to have been used in audio valve amps.
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.
