Small Audio Power Amplifier Using Op-Amp and Two Transistors
https://www.deeptronic.com/electronic-circuit-design/small-audio-power-amplifier-using-op-amp-and-two-transistors/
Figure 2. Schematic Diagram of Small Audio Power Amplifier Circuit Using Op-Amp and Two Transistors. Let’s imagine the op-amp is omitted, then the base-to-base voltage is the voltage between R4 and R5 which is dropped by two diodes D1-D2. This voltage is slightly higher than base-to-base bias requirement to produce small leakage current when ...

Recommended: 40W transistor audio amplifier circuit with PC B. Which this C2, also helps to make the voltage at the emitter pin or the potential voltage at point D more smooth (from Figure 1). We only limit the sum of the feedback. Because in the basic amplifier circuit, High magnification is more important than high clarity.

This is a 4 transistor audio amplifier circuit. Which is a 4-transistors complementary push-pull amplifier, that shows the basics of audio amplifier design. This circuit saving on battery current, which is quite low with middle volume, rising to 25 -30mA as a volume is increased. This gives us a 250 mW amplifier

Transistors are used in audio amplifiers in different ways. You have discrete class-a circuits that overdrive well like the infamous Neve console mic pre. On paper an op amp designs will have the best performance (actually putting separate transistors in front of a conventional op amp is probably going to get close to the theoretical limit of ...
Best sounding transistors - High-End Audio Discussion Forum

The number of output transistor an amp uses can dictate how well it moves the speaker. For example, when you compare an amp with 4 output transistors (2 for positive waveform and 2 for negative waveform) with an amplifier that has 12 output transistors, the transistors on the 12 amp will work 1/3 as hard for the amp to push the same amount of ...

The triode vacuum amplifier was used to make the first AM radio. Early audio power amplifiers were based on vacuum tubes. Whereas, now-a-days transistor-based amplifiers are used that are lighter in weight, more reliable and require less maintenance than tube amplifiers. Applications for audio amplifiers include home audio systems, concert and ...
