    Hi guys

    I am designing to 200w PA amplifier and it have to run off from a 12v car
    battery. I planning to use a pair of power mosfets to drive a step-up
    transformer in a push -pull configuration. The speaker is 11 ohm and the
    audio frequency response is about 300hz to 5khz . My problem is designing
    the transformer, I don't have much knowledge in transformer design and I am
    wonder anyone could point me to web sites or have a calculation example they
    can lighten me



    Thanks

    I know of this really good site, but it is in German. Not too difficult to
    translate though. Calculates the complete transformer.
