<P>PROBLEM TO BE SOLVED: To provide a DC power stable supply device for a musical instrument that enables a DC power source for an amplifier, an effector, and a tuner to freely be used without adding extra DC power supply cables, eliminates the need to mind a voltage drop and a consumption time, and makes it possible to use devices such as a high-performance amplifier and an effector, and to provide an amplifier with the DC power stable supply unit. <P>SOLUTION: The DC power stable supply unit and the amplifier with the DC power stable supply unit use a stereophonic jack on the side of the musical instrument through an ordinary stereophonic cable and is provided with a DC power stable supply plug and an AC adapter on the amplifier side or the DC power stable supply jack and an AC adapter with a DC voltage varying mechanism for an amplifier main body. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
