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 …

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 ...

Fig 11.4.1 Small audio transformer. 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.

Line Output. Typically, audio transformer is driven by an amplifier and loaded by several thousand pF cable capacitance and high input impedance of line receiver. Therefore, a line output transformer should have low output impedance which remains low at high frequencies. This requires both low resistance windings and very low leakage inductance. 5.
Valve Amps: Output transformers - Lenard Audio

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.

The Audio Note Transformer Design Philosophy Article By Andy Grove And Peter Qvortrup . The Theory The electronic valve is a high voltage, low current device that is incapable of driving a low impedance loudspeaker directly. Although output-transformer-less (OTL) designs have appeared from time to time, with these types many devices are connected in parallel and a large amount …

eg single ended 2500 ohms primary. turns = 33 x root of 2500 = 33x 50 = 1650 turns, 5 layers prim, sec, prim, sec, prim. not sure about air gap, there is SOME info on the web. the primary turns is a simplification of the classic transformer equation, viz. B= (1.10 ^8 x volts) / 4.44 x Frequency x Area x turns.
