My cause of construction of this project was to develop a compact design for a stereo amplifier can be integrated by a wrong (but the sound quality conscious!) Living student at a university or a college dormitory. audio amplifier 50W circuit The amplifier feeds a pair of speakers with two LM3876 amplifier integrated circuits (50 watts [...]
Simple Class A amplifier circuit This circuit is that of a simple class A audio amplifier. But with zero distortion, Q1 is a switch in the on or off, so that no load current by the resistance R2. In the best case, the tension in Q1 and the load resistance must be equal to the [...]
800W audio amplifier circuit The audio power amplifier ideal for home user or PA work or for use as a general-purpose subwoofer or hi-fi amplifier. There are many people like to prefer MOSFET as their legendary ruggedness. This circuit project had the Mosfet amplifier module which produced 800 Watt into 4 Ohm speaker load and so we decided to take a look it. It was turned [...]
Here is a 60 to 100 Watt Amplifiers circuit, the electronic designer was developed for the (relatively) easy to build at a reasonable price. It has a better performance (ie: musical quality) than the default STK module amps, in practically every mass market stereo receiver manufactured today. As I am behind this thing, it was [...]
Portable and small unit, Can be built on a veroboard Firstly, I’d like to stress that the intended use of this circuit is only one of many possible applications. Apart from the obvious usage as a headphone amplifier, the circuit can be used for a range of applications where a wide bandwidth low power amplifier [...]
Small but powerful multipurpose amplifier This small amplifier is constructed around the TDA2003 IC, capable of delivering 4Wrms at 4ohms. The TDA 2003 has improved performance with the same pin configuration as the TDA 2002. The additional features of TDA 2002, very low number of external components, ease of assembly, space and cost saving, are [...]
3V Battery powered, High Performance unit This amplifier can be directly connected to CD players, tuners and tape recorders. It is tested with several headphone models of different impedance: 32, 100, 245, 300, 600 & 2000 Ohm.Schematic shows left channel only. B1, SW1, J1 & C3 are common to both channels. R3 value was calculated [...]
