Power Amplifier OCL 100w With MJ802 MJ4502

Description: Main Power Amplifier OCL 100 watt using MJ802 and MJ4502 transistors. It is designed to provide strong bass and bold treble, making it suitable for various applications such as parties or home theater systems. This Class AB amplifier delivers a power output of approximately 100 watts at an 8-ohm load. An essential consideration for this amplifier is the power supply requirements, which must provide approximately +38V, GND, and -39V, with a current rating not falling below 3 amps per channel. The circuit is moderately detailed, which may not be convenient for novices; however, a PCB model is available for easier assembly. This amplifier is designed for those who appreciate high-fidelity sound reproduction. Additionally, for those interested in a bipolar transistor power amplifier circuit, the HIFI OCL 100W RMS model is a compelling option. Key transistors for this design include BD317 and BD318, with alternatives such as BD139, BD140, and BC556 being readily available. The power supply voltage can be set to 35V, facilitating straightforward construction.

The OCL (Output Capacitor-Less) amplifier design is notable for its efficiency and simplicity, making it a popular choice among audio enthusiasts. The use of MJ802 and MJ4502 transistors ensures robust performance, capable of delivering high power output while maintaining sound quality. The Class AB operation allows for a balance between efficiency and linearity, reducing distortion and improving audio fidelity.

The power supply requirements are critical to the amplifier's performance. A dual power supply providing +38V and -39V is necessary to achieve the desired output levels without distortion. The current rating of at least 3 amps per channel ensures that the amplifier can handle dynamic audio signals without clipping, which is essential for maintaining sound quality during peaks in audio playback.

The circuit design incorporates various components that work together to achieve optimal performance. For instance, the biasing network ensures that the transistors operate in their linear region, minimizing crossover distortion. The output stage typically includes a complementary push-pull configuration, utilizing the MJ802 and MJ4502 to drive the load effectively.

For assembly, a printed circuit board (PCB) can simplify the process, especially for those who may not have extensive experience in circuit building. The availability of a PCB allows for a more organized layout, reducing the likelihood of errors during assembly and ensuring reliable connections.

Overall, this OCL 100-watt amplifier circuit represents an excellent choice for those seeking a high-quality audio amplifier that delivers both power and fidelity, suitable for various audio applications.Main Power Amplifier OCL 100watt by MJ802, MJ4502. May pleasing of friends at like firm bass and Treble be bold. Because it is Amplifier OCL model Class AB. And it has electric tall power about 100Watt at 8ohm size loudspeakers. Then can use in the work party or in the system home theater get comfortablely. Important aspect be power supply Source must have enough about +38V GND -39V that Current do not lower 3 Amp per Chanel. When see the circuit has moderately detail. Then not convenient for a novice for the convenience and friends have model PCB give friends see with. Have a good time with sound of sweet-sounding music, please sir. If friend want Bipolar Transistor power Amplifier Circuit. , In model HIFI OCL 100W RMS. I sizes think this circuit may is the one choice interesting, use Transistor the important be BD317 and BD318 unless have transistor number BD139, BD140, BC556 then seek buy easy, when see power supply use voltage source 35V just then build not difficult For other detail as a result the a few See in Circuit.
