    You need to have a power supply. Are you hoping to use a battery, or plug it in? And what is your load, a big bass speaker cone?

    You're interested in an algorithm for calculating a 20W audio amplifier? Or you just looking amplifier circuit diagram to build it?
    If you want to build an audio amplifier then I recommend you analyze the project attached. Contains all necessary information. It is a simple design, compact and Hi-Fi.

    A 20W amplifier will not provide a lot of bass but it should be fine for a practicing in a small room.

    I want to plug it in, All what i need is the circuit in order to build it, bass guitar works with 20Hz minimal, I Need a circuit that i can use it with volume and some effects as options.
    for the first sight, It will be a transformer, many power amplifiers...
    So, Any Ideas ?

    Fender Bassman 6G6 schematic. You can leave out the , "normal" channel.

    For fun!

    Sure, but one may want to design some frequency shaping into the amp, including adjustable EQ. By the way, your link is a DC converter.

    TomJoad, have you visited DIYAudio.com? I bet you'll find lots of amp circuits and help there.

    @TomJoad

    Welcome to AAC.

    Do you want a safe (simple?) lower voltage circuit design to start with, or do you have the experience, knowledge and respect to work with high voltage circuits??

    Yep, this place does that some times: I post a link and it grabs the previous one I posted in another thread. Have no idea why.
