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 …

DESIGN OF AUDIO TRANSFORMERS. Most important elements in the design of an audio transformer are the selection of core type, size and material, turn ratio, windings and casing. a) Core Size & Material. Choice of core size and its material depends upon frequency response, power levels, and harmonic distortion.

transformer is not a complex device, considerable explanation is required to properly understand how it operates. This chapter is intended to help the audio system engineer properly select and apply transformers. In the interest of simplicity, only basic concepts of their design and manufacture will be discussed. 1.1 Basic Principles and ...

Audio Frequency (AF) Transformers work at frequencies between about 20Hz to 20kHz and are used in audio amplifier circuits, they were essential in valve (tube) designs for matching the high impedance outputs of theses amplifiers to low impedance loudspeakers, but transistor amplifiers have much less need for output transformers.

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.

For the purpose of design demonstration, assume that a plate modulation transformer is required for the following conditions of operation. 1. Modulator output is push-pull pentodes requiring load impedance of 10,000 ohms and that each tube draws 60 ma. plate current. 2. Audio output power to be 7.5 watts. 3.
