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,

Audio transformers must utilize both high-permeability cores and the largest practical number of coil turns to create high primary inductance. Coil inductance increases as the square of the number of turns and in direct proportion to the permeability of the core and can be approximated using the formula: L = 3.2 N28 ì A / 10 R

ImpedanceIn Audio Transformers Winding Methods In previous papers, we’ve delved deeply into how Lundahl differs in design and manufacturing, in the quest to make the ultimate transformers for audio applications. But to briefly recap: the majority of transformer manufac-turers use bobbins and winding machines that can be purchased for a price.
