    Hello, i am searching for FM amplifier power of 5 to 10 watts, can anyone
    give me or suggest what schematic to use, and please, let it be simple. If
    is it possible, give me links only to amplifiers who work on 12VDC. Thanks
    and sorry on bad english

    What frequency? 88-108 MHz?
    Where do you plan on using this?

    So why not build a 5-10W amplifier for one of the ham bands rather than the FM
    broadcast band? That way it'll not only be legal, but if you want to make
    your life a little easier you can build an HF amplifier and not worry about
    "proper" RF design as much (i.e., everything will still behave very closed to
    a "lumped" element and you won't have to worry about parasitics nearly so much
    or figure out clever ways get rid of those 100fF capacitors that your filter
    design program says you need...)

    The ARRL handbook has *many* amplifiers in it.

    If you're in the US, you would be violating the law with this output

    Also, your Amateur license from Croatia is irrelevant, unless perhaps,
    you were building this in Croatia.

    Or, you could operate it inside a shielded enclosure or screen room,
    or into a resistive dummy load. The key is to limit radiated
    emissions. In the US, you can't broadcast on 88-108 MHz with any
    appreciable power without a license. Research FCC Rule 15.209 for
    more assistance.

    Since you are already in school, perhaps you should consider taking a
    course in Engineering Ethics.

    Not only are you willing to violate the law, you are asking folks here
    to help you do it.

    They don't have laws in the former Yugoslav republics, not since Tito died.

    don't worry about it for 15 minnutes it will cause hell nearby not all over croatia. 10 watts is a lot of fm power and i am asking myself what kind of a teacher will let you do that. a 1w for a class demonstration is plenty good and for a 15 minutes and bever again? is just plain stupid. rasumi whala noche.
