MOSFET Audio Amplifier circuit 70 Watt power output This is use the MOSFET power amplifier circuit, amplifier circuit has a very good sound quality. With the noise is quite small, thus making the amplifier circuit is suitable for you to try. Here's the circuit. Click to view larger.  Power amplifier with a 70Watt power is able to issue a clear voice, and very and good loud.

Several LED above and other components used to determine the signal amplifier, when in a state of high and low . If the signal received from the amplifier circuit is high then the LED lamp are lit up everything and more bright LED lamps, but otherwise if the received signal is low then the lights on only one or two , even absent or faint. To use the circuit you can connec with the output amplifier or speaker output , if there is reinforcing the other in the amplifier , can be connected to the output.

Although the output of which was issued in this circuit only 35watts maximum, but th esound can be issued harsh , loud , and clear. If the voltage is fit and clean , how to assembly , components are good , the right speakers , this circuit will definitely make a sound that good to hear the ear. See audio amplifier circuit  below : Technical Information : Vcc Max = 45V Vcc TYP = 30V Po            = 35W RL           = 8Ohm Icco TYP = 40mA Icco Max = 80mA I Max      = 10A The amplifier can use to : tuner , subwoofer surround amplifier , surround amplifier , subwoofer system , car amplifier , PC amplifier , DVD/CD amplifier , Room amplifier .

This is a design schematic Class A power amplifier . This is a close as possible in operating parameter  the  Under Classes is class B , to aid comparison ; in particular the NFB factor remains 30dB at 20 kHz. The front end is similiar to class B amplifier. This circuit uses a standart quasi output. This may be replaced by a CFP stage without problems. In both cases the distortion is extremely low, but gratifyingly the CFP proves even better than quasi , confirming the simulation results for output stages in isolation. About Class-A amplifier , in this class is the highest class from another class. Classes below begin from AB to Class S. In a Class-A amplifi er current fl ows continuously in all the output devices, which enables the nonlinearities of turning them on and off to be avoided. They come in two rather different kinds, although this is rarely explicitly stated, which work in very different ways. The fi rst kind is simply a Class-B stage (i.e. two emitter-followers ...

There are possible alternative input stage transistors, the Toshiba 2SA970BL and 2SC2240BL, which appear to be good substitutes for the Hitachi 2SA1085E and 2SC2547E. The ‘BL’ suffix is the high gain group. Alternatives for the Sanyo 2SC2911 and 2SA1209 are the Toshiba 2SC3423 and 2SA1360. 70W Mosfet power amplifier Circuit Diagram This 70W power amplifier is designed for quality rather than quantity, and if much higher power is really needed there are other more suitable design approaches. This is an awesome amplifier circuit, and this is the older version�(MJR7-Mk3). There is new version released (MJR7-Mk5) for better quality and performance, just go to THIS PAGE for complete circuit explanation. source

Power amplifier has up to 1000 Watt power, this circuit made one channel only so if you want to create a stereo in it must be made one again, actually this is more suitable power amplifier in use for Sound System or outdoor, so if only in use for the house I think is less suitable. Maybe you've seen or even have an active speaker and there is written 1500 watts PMPO (Peak Music Power Output), make no mistake this is different from Power Amplifier Active Speaker, I often dismantle such Active Speaker in it only a power with power no more than 150 watts by using the transformer 2-3 Ampere. PMPO is not a real power which is issued by the Power Amplifier, but counting all the speakers that there is, for example: if there are 5 pieces of speakers on each channel and each speaker has a power of 10 W then it is 100 W PMPO. 1000W Power Amplifier schematics Part List 1000W amplifier While this 1000 Watt Power Amplifier minimal use transformer 20 Ampere.
