Sell 150Watt MONO SONYA 020 Power Amplifier best price

150Watt MONO SONYA 020 pcb Power Amplifier - using voltage 45-65VDC. - size and items according to the picture. - using type TIP41 and TIP42 Transistor drivers or similarities. - using the Final Transistor type 2N3055 and MJ2955 or similarities. - it 's suitable for home Power class ber Diy A class AB power amplifier set is on the DC offset input stage and the vase (central block) bagain. Where the potential meter DC offset (front) is used to set the DC offset on the output line to the speaker to get the DC offset close to 0-volt, or should be below 20 millivolts. The way he used the multimeter on the DC voltmeter on the DC 2.5V range. Then put the red settings needle on the speaker 's output, while the black needle is connected to the parent grounding star. Then set the potentialo meter DC offset (front) until it gets the lowest DC offset (near zero or below 20mV). The system is usually located in a vases or central block of power amplifier. Set the multimeter on the ampere meter set to 500mA. Then release the Vcc cable and connect the power supply series - red multimeter needle - multimeter - black multimeter - power amplifier. power amplifiers and set it up to a multi meter pointing at 50ma. More quality audio / sound. The larger the current the bias will be the better the quality of the audio, and the more heat the power amplifier will be, the more you have to pay attention to or increase the size of the aluminum cooling transistor.
