    Can anyone help me in making a class AB push-pull amplifier using 4 transistors(same type) with output of 30Watt RMS. (diagram/layout)
    thank you very much..

    or can someone teach me about designing amplifiers? ty

    hi there ....... i had been workin on several amplifier designs....
    i;d bn workin on 16 mhz signal amplification ..... input 0.5v, 1mA, o/p 2A, 0.5V
    using 2 transistors..... CE and CC configuration
    c945, bc 108 or 109
    i refer you to the book electronic devices by floyd, i have sixth edition..... u cn design wht u want !

    Is this a homework assignment?

    Why not do it a more robust and simplified way as per the attached LTSpice schematic.

    Please note that I just threw that together, none of the gains etc.. are correct to your application. Play with it.
