Amplifier circuit stereo audio with good power, using integrated circuit TDA7293 for up to 2x 100 Watts. With Suggested PCB mounting design. Includes power supply to the circuit itself, thus only requires a transformer to power. PCB compact size even being single sided. Allowing mount a power amplifier and compact with good quality, ideal for various applications.

Includes power supply on board, only requires a transformer to power the circuit.
The part of the power supply uses bridge rectifier, large electrolytic capacitors to filter values ​​can be used since the 4.700μF to  12.000μF. The LEDs in series with the resistor and indicate on state, serve to discharge the electrolytic capacitors.
Includes circuit mute / stand-by, but was not placed key to turn on and off, is to avoid clicks in the speakers on and off, being unnecessary to use the relay output.
The power transformer can be from 18-0-18 to 33-0-33 / 200VA, with transformer with lower voltage may need less current too

  1. ME PARECE BIEN
    cual es el propósito con los circuitos de audio hay otros que interesen o que sean mas industrial
    esa es una forma de informarse bien espero que sigan asi proporcionando ideas pronto nos comunicamos
    que estén bien Sres

  2. where can i buy the whole PCB and component of this audio amp. i myself will assemble it. please help me i am very much interested in this stuff..thank you very much

  3. I have no any idea or experiance about this all.but i want to learn to build it self.truly i,m most lover of this simple circuit amp controller and most for high watt capasity.so guy, i cant build it and wont make any deal with china.you all know it why,.well if somebody agree and want sell own project (finish good) to me should reply me on angkp06@gmail.com.
    No metter what of value been set by you.

    Deal guys.good conditions for good price.

    BOOOM LOVER
