Output Transformer Impedance

https://www.radioremembered.org/outimp.htm

The function of the audio output transformer is to transform the high impedance of the output tube to match the much lower impedance of the speaker. This is necessary to get an efficient transfer of the audio signal to the speaker. The output transformer as an impedance matching device, works on the principal of reflected load.

TRANSFORMERS. 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.

The output transformer is an important part of the amplifier requiring a thorough parameter determination. Building an amplifier is an important step in the experimental part of the project. 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 …
