50W Audio Amplifier Circuit

An audio amplifier is an electronic device designed to amplify low-power audio signals, which primarily consist of frequencies ranging from 20 Hz to 20,000 Hz, the human range of hearing. This amplification is necessary to drive loudspeakers and represents the...

Audio booster

The amplifier's gain is nominally 20 dB. Its frequency response is determined primarily by the values of a few components, mainly C1 and R1. The schematic diagram values provide a response of ±3.0 dB from approximately 120 Hz to over...

Flame Feedback

Flame Feedback is a sound sculpture constructed from a speaker driver, a candle, and electronic components. The speaker is activated with a low-frequency tone, which moves air and causes the candle to flicker. An optical sensor detects the flicker of...

help me identify this amp

A long-time observer has acquired four vintage amplifiers for their enclosures, but with limited knowledge of older equipment, they have not made much progress. The project involves the restoration and utilization of vintage amplifiers, which typically feature discrete component designs and...

complete 70 watt power amplifier schematic

The circuit power amplifier depicted is a schematic design for a power amplifier with an output power of 70 watts, operating in Class AB mode. This power amplifier circuit is equipped with a tone control circuit. The 70-watt power amplifier...

Fast Audio Peak Limiter

The circuit devised by Phil Allison still has some input voltage limitations, since it is based on a FET. Junction FET VCAs also create considerable distortion, with the worst of it appearing when the signal is attenuated by 6dB. The...

Simple Audio Test Oscillator Circuit

An 88 mH surplus telephone toroidal coil is utilized in a 1 kHz oscillator. It can provide up to 8 V peak-to-peak into a high-impedance load. The total harmonic distortion (THD) is 0.9%. The circuit employs an 88 mH toroidal coil,...
