Frequency response of audio transformer and high frequency transformer (1) the output voltage of the two side of the transformer varies with the operating frequency. (2) When the intermediate frequency output voltage of the transformer is U, when the output voltage (input voltage remains unchanged) drops to 0.707U, the frequency range is called the transformer passband B.

In audio transformer applications, magnetic saturation causes low-frequency harmonic distortion to increase steadily for low-frequency signals as they increase in level beyond a threshold. In general, materials with a higher permeability tend to saturate at a lower flux density. In general, permeability also varies inversely with frequency.

Valve Amps: Output transformers - Lenard Audio

The distortion figurers and frequency response of Valve amps are often specified at 1 Watt. Most output trannys can easily achieve a bandwidth of 20Hz to 20kHz at 1 Watt. But this bandwidth is rarely achieved at full power. The low frequency response at full power is directly proportional to the number of primary turns and mass of the iron core.

In an output transformer, the low frequency response is largely governed by the size or mass of the stack. The bigger the stack, the lower it will go without saturating. (That’s why an SVT weighs so much, its OT is the size of a Oldsmobile!).

Testing the Mullard 5-10 Output transformer – Primary Windings

https://primarywindings.com/2018/07/08/testing-the-mullard-5-10-output-transformer/

Mullard 5-10 output transformer frequency response. As can be seen the response is very good indeed. The -1dB points being taken as 4Hz and 60KHz. The measured leakage inductance was measured as 5.5mH, So we are very pleased with the results. It is an excellent transformer, and is now available here.
