Description
@
The stereo record player put on the market at a price point for which it is easy to ask taking advantage of the technology adopted as PL-4.

The hysteresis synchronous motor is adopted as a motor, it is strong for a voltage, a load intensity, etc., and the more exact rotation is realized.

The thing of precision finish of the diameter of 30cm, the weight of 1.4kg, and an aluminum casting is adopted as a turntable.
Moreover, the lower end of the shaft was made into the cone, and a bearing is considering it as a precision manipulation of gun metal, and has realized the more exact rotation.

The dynamic balance type is adopted as a tone arm.
A dynamic balance type applies zero and a stylus force by a spring with special weight of the pickup [ itself ]. Thereby, it becomes constant [ the pressure of the needle point ] and the stylus force which carried out equal to each sides of the sound track is given.
Moreover, the cartridge attachment has been Japanese Industrial Standard and EIA specification.

PL-C1 which is man-month type cartridge is adopted as a cartridge.
The splitting oscillation in a high region is reduced by planting a 0.7mil diamond needle, without having reduced the mass of vibration system to the cantilever currently planted in the needle using the duralumin pipe of 0.6mmphi, and also crushing the leading end of a pipe. The cylindrical magnet which excelled [ this ] in the crosstalk is combined.
