    So i have a project to be built that requires PS that has 4 Amps near 15V

    I have a vonage PS 12VDC 1.5A

    I can use it though i cannot use the amplifier im building that loud..

    At first i thought of using transistors but i think it would violate a law (not a country law but something related in electronics)

    you would have to rebuild the rectifier in the power supply.

    Your best bet would be to just get a new power supply...

    Quick search on Digikey comes up with this looks to be aroud $30

    Assuming your "vonage" power supply is a wall wart, there is nothing you can do to increase the voltage or the current . You're right about trying to violate the laws of physics.

    You can also get 15V >4A laptop bricks all over Ebay for under $10 all day long...
