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 …

Valve Amps: Output transformers - Lenard Audio
https://education.lenardaudio.com/en/14_valve_amps_5.html
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.

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, most notably the input and output …

Although C-core audio transformers for tube amplifiers have had fairly wide acceptance (at least in Europe and Japan), C-core power transformers are not common in audio equipment. Photo 8 shows a medium-power C-core power transformer, a single-loop transformer with windings on both legs of the core. R-Core Transformers
Audio Transformer, its Types and Impedance Ratio
https://circuitdigest.com/tutorial/audio-transformer
An Audio transformer with Step-up feature will step up the voltage or the current level to drive a load across it. Same happens for the Stepdown transformer too. It converts the voltage from higher to lower with the increased current output. The audio transformer also provides impedance matching specifications. When the output of one circuit or device is …

The Defining Component of any Valve Amplifier. . The Output Transformer is, without doubt, the single most important component in any high quality valve amplifier. It is impossible to make a truly exceptional amplifier without investing in the best possible Output Transformer, which in turn must be correctly designed for the circuit and valves being used.

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.
