Audio Transformers - Learn About Electronics
https://www.learnabout-electronics.org/ac_theory/transformers04.php
Audio transformers often perform several functions at once: Where used, they allow the AC audio signal to reach the loudspeaker whilst preventing any DC from the amplifier... They provide an isolated external connection for the loudspeakers, improving safety. They …
Audio Transformer, its Types and Impedance Ratio
https://circuitdigest.com/tutorial/audio-transformer
Audio Transformer uses this isolation property and creates isolation between the output speakers or audio circuitry with the transformer’s input side amplifier system. In such case, 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 Transformers. Audio transformers can: 1) Step up (increase) or step down (decrease) a signal voltage; 2) Increase or decrease the impedance of a circuit; 3) Convert a circuit from unbalanced to balanced and vice versa; 4) Block DC current in a circuit while allowing AC current to flow; 5) Electrically isolate one audio device from another. While transformers are useful in …

Transformers for Audio
https://sound-au.com/articles/audio-xfmrs.htm
Nearly all valve (vacuum tube) amplifiers use a transformer to reduce the relatively high impedance of the valve plate to something useful for driving speakers, and high quality microphone preamps and mixing desks either use mic (and/or line) transformers as a matter of course or offer them as an option.

The R-core transformer has the potential to become the predominant choice for use in audio equipment, providing all of the benefits of toroidal transformers at a lower cost. EI Versus Toroidal Transformers — A Case Study I did some real-world comparisons of EI and toroidal transformers in the recent design of a tube headphone amplifier.

That's not an audio transformer, that's a power transformer which likely came from an audio amplifier. Audio transformers are used for impedance matching the audio signal itself. Thanks. Out of the blue, for about 15 seconds, it made …

Some tubes will state the audio transformer suggested impedance at typical 5% distortion. No suggestion of an audio transformer seems to exist anywhere for the 201A. I am using a 5K to 8 ohm transformer but getting a little distortion. My speaker is 3.2 ohm so tube is seeing 2.5K for now. I bought 8 ohm replacement speaker to get back to 5K.
