    sorry to start this topic.. im new here...and im not sure if this has been discussed before..

    anyways...i want to start building amplifiers..professional amps...not the ones u build for a dollar....im talking about ones you can sell..and make money....

    one of my friends has a audio place and i want to start working with him...

    i dont know how hard it is to make one of these pro amps..but i can try...

    please link me to any websites that you know....
    or a circuit diagram with parts list so i can build one...

    thanx:)

    Do you want to learn some theory first, or just jump in?

    What is your targeted wattage range? I don't even want to touch the tubes vs. solid state debate.

    Check out Elliot Sound Products:

    Lots of DIY ideas, PCBs and some kits.

    Better to start out with solid state. Tube amps have high voltages, and the parts are pretty expensive nowadays.

    SgtWookie,

    I don't think these circuits are professional designs. They use a differential input pair with discrete transistors which is not working well because the transistors, even they are the same, are non matched to a high degree. It would be better to use a ready op amp which performs much better than these two discrete transistors.

    Many people make The Gain Clone audio amplifier (look in Google). The ICs cost only $6.36US for each channel.
    A guy in New York makes a stereo amp with them and sells hundreds for $4000.00US each!
    Of course it has a fancy volume control and case plus a power transformer, rectifier and filter capacitor.
