PURPOSE:To make the sound quality of a compact disk smooth and clear without changing the using method of a general acoustic equipment by connecting a Mobius winding coil in parallel with a ripple filter capacitor provided in a power supply circuit of an acoustic equipment via a diode. CONSTITUTION:A Mobius winding coil 6 is connected in parallel with a ripple filter capacitor 8 in a power supply circuit 7 of a premain amplifier 13. A diode 9 is connected between the ripple filter capacitor 8 and the Mobius winding coil 6 so as not to apply voltage of the power supply circuit 7 to the Mobius winding coil 6. Here, three Mobius winding coil 6 are used. In one coil, a Mobius winding coil 6b combining two elements of a dielectric right Mobius winding coil 6a and a magnetic left Mobius winding coil 6d, and Mobius winding coil 6 combining four elelments of a magnetic right Moblus winding coil 6c and a magnatic left Mobius winding coil 6d, are used. |
