BLAZER 1000 WATT POWER AMPLIFIER CIRCUIT DIAGRAM

BLAZER 1000 WATT POWER AMPLIFIER CIRCUIT DIAGRAM

The transistors are 2SC3858 (NPN) and 2SA1494 (PNP), and feature high bandwidth, excellent safe operating area, high linearity and high gain. Driver transistors are 2SC5200 (NPN) and 2SA1943 (PNP). All devices are rated at 230V, with the power transistors having a 150W dissipation and the drivers are 50W.

This circuit describes an amplifier, power supply and tests procedures that are all inherently dangerous. Nothing described in this article should even be considered unless you are fully experienced, know exactly what you are doing, and are willing to take full 100% responsibility for what you do. There are aspects of the design that may require analysis, fault-finding and/or modification.

600 WATT DARLINGTON POWER AMPLIFIER SCHEMATIC DIAGRAM

600 WATT DARLINGTON POWER AMPLIFIER SCHEMATIC DIAGRAM

This Power amplifier circuit produces output power up to 300 watts ( 8ohms) pada masing-masing channelnya. It is a high fidelity audio power amplifier. Designed for demanding consumer and pro-audio applications. You can also use this circuit with AV receivers, Audiophile power amps, Pro Audio High voltage industrial applications etc

Amplifier output power maybe scaled by changing the supply voltage and number of output devices. The circuit includes thermal shutdown circuitry that activates when the die temperature exceeds 150. CIRCUIT mute function, when activated, mutes the input drive signal and forces the amplifier output to a quiescent state.

POWER AMPLIFIER MJ15003 - MJ15004 CIRCUIT SCHEMATIC DIAGRAM

POWER AMPLIFIER MJ15003 - MJ15004 CIRCUIT SCHEMATIC DIAGRAM

When I began the design of this amp, my goal was to make a product better suited for the reproduction of complex music and voice. Although I emphasize the high electrical properties, the most important requirement is to create a superior sound, vivid images and superb spatial aural clarity.

Although the average level of listening is usually less than 10 watts, my design concept was to an amplifier with plenty of reserves, but the deviation is for Class A, at the height of the audience of cross-over distortion at a very low level. There is no place in the pathway, enhances the precision of the tonal characteristics of instruments and voices clearly. This Amplifier is virtually zero phase distortion over the audio range resolution is perfect and completely color the sound.

500WATT POWER AMPLIFIER CIRCUIT SCHEMATIC DIAGRAM

500Watt Power Amplifier

There are some important updates to this project, as shown below. Recent testing has shown that with the new ON Semi transistors it is possible to obtain a lot more power than previously. The original design was very conservative, and was initially intended to use 2SA1492 and 2SC3856 transistors (rated at 130W) - with 200W (or 230W) devices, some of the original comments and warnings have been amended to suit.

Note:

    * This amplifier is not trivial, despite its small size and apparent simplicity. The total DC is over 110V (or as much as 140V DC!), and can kill you.
    * The power dissipated is such that great care is needed with transistor mounting.
    * The single board P68 is capable of full power duty into 4 Ohm loads, but only at the lower supply voltage.
    * For operation at the higher supply voltage, you must use the dual board version.
    * There is NO SHORT CIRCUIT PROTECTION. The amp is designed to be used within a subwoofer or other speaker enclosure, so this has not been included. A short on the output will destroy the amplifier.

This is 80Watt power amplifier OCL circuit using devices pillar is the integrated circuit LM12. This interesting routes many good bass and treble alive. If a friend is the CD therefore has a beautiful voice and Pre Tone Control is good that some will take something very magical. Importantly should choose Power supply source, which has been fairly high voltage class 38Vdc GND 38V-3A is the current low level. To decorate the fines resulting from the size finely R4 2 ohm/4W Idle current about 30mA, or with the whole center just before. Almost forgotten friends should choose the material is good, good, especially IC LM12 and Transistor everyone.

HI-FI POWER AMPLIFIER 12 VOLT CIRCUIT DIAGRAM

The voltage drop across the resistors R2 and R3, are used as the input of the Darlington pairs.
 As the input current to the op-amp depends on the level of the signal op amp is amplifying
the voltage drop across the resistors R2 and R3 will be proportional to the input signal.
These voltage drops are given to the base of Darlington pairs. The amplification is stabilized
as a result of the negative feedback from the junction of collectors of Q2 and Q4.
The theory may seem little awkward for you.But its working good.Such a simple but stable
circuit as this can produce a reasonable output of 12W on a 4 Ohm speaker.
