Abstract
PURPOSE:To zero the stray capacity of the shield wire, by delivering the singal of the signal source through the core and the second shield external sheath to other electric circuits and keeping equal the potential of the core and the first shield external sheath with the potential ofthe core at all times. CONSTITUTION:The shield wire 11 is constituted that the external sheath 13 made of insulation material such as synthetic resin is covered on the core wire 12 made of coper wire, the first shield external sheath 14 consisting of net copper wire is covered on the sheath 13, external sheath 15 is made of insulation material is covered on the first shield external sheath 14, the second shield external sheath 16 is covered on the sheath 15, and the second shield exterinal sheath 16 is covered with the external sheath 17. When this shield wire 11 is used for the signal path feeding the output signal of the pickup cartidge to the preamplifier 21, the potential of the first shield sheath 14 is kept equal to the potential of the core wire 12 at all times with the circuit incorporated in the preamplifier 21. As the result, the stray capacity can be neglected.
