This amplifier circuit has a pretty good quality. Of course the sound quality, although this one amplifier does not have a large output power but in terms of soft and loud voice that this amplifier can be unreliable. With a single IC capitalize MPC576H and several other supporting components you have to make this amplifier circuit. Voltage at least 9 Volt and 24 Volt Max. Output Power 3.5 Watts with 8 Ohm impedance. Good Quality Sound Amplifier Circuit

Transistor are the components that have never missed on any electronic circuit . To determine whether the quality is still good or is damaged then need for testing of the transistor . This test is needed before it is installed in an electronic circuit to avoid disappointing results in the future. Thus , all transistors are mounted has been declared unsuitable for use . Please note that th e damage was not located from the transistors can not stand the temperature is too hot . Therefore emphasized here for use tongs as a heat barrier when soldering each feet transistor. Part List : R1=47R R2=100R R3=Resistor with adjustable  to the current Vr1=10K trim Q1=Transistor socket S1=Saklar on/off G1=3V battery To facilitate testing , the provided holes for the third feet on the transistor Q1. At thefoot of the emitter is connected to the battery (+). Base associated with Vr1, and the collectors associated with R2. The voltage (-) that enter the R3 give ampMeter to check quality of the tran...

Here are some tips you need to note: 1. Pick of the power that suits your needs. For personal use such as exercise, etc., is sufficient to choose an amplifier with a power of 15-20 watts. In most small power amplifiers are already available facilities such as Head Phone jack (eg Guitar Amplifier Laser 20) which is very useful especially for young people who have a habit of playing music until midnight. By leveraging these channels to Head Phone, then secured another household or neighbors will not be disturbed our music sound. Sound good hasilnya.Apabila amplifier system we will use to train together in a full band with drums, etc., then you should choose a larger power amplifier that is 70 watts or above. Thus the sound produced from the amplifier and sound system will not be drowned by the sound of pounding and pounding beat Drum.Untuk use on stage, you will need a higher power that is at least 125 watts or more, because this amplifier will be able to once we use as a monitor of musi...
