Hitachi HT-67

Description

The Hitachi HT-67 features a quartz lock servo feature incorporated in the Unitorque motor which is characterized by a torque which is generated in principle uniformly and by smooth constant speed rotation. As a result, a superb speed accuracy and high signal-to-noise ratio are produced.

The tonearm has a special chemical treatment which creates microscopic fissures on the inner surface of the stainless steel pipe and when vibration is transmitted to the tonearm, the fissures attenuate the vibration as internal friction takes place between the crystal grains of the steel structure.

A special DC motor is adopted to drive the tonearm and this is accompanied by a fully automatic mechanism which has absolutely no effect on the rotation of the platter.

A no-contact electronic system is used for the automatic return detection upon completion of disk play. This means that no lateral force is applied to the stylus tip and that there is no ensuing distortion.

By employing the HARC compound with its high specific gravity for the cabinet, undesirable vibration is kept down to the bare minimum and acoustic feedback is improved.

A gimbal support system is adopted for the bearing construction of the tonearm for reduced rotational resistance and superb traceability with a light tracking force performance.
