Equipped with virtual battery operation that provides the same operating capabilities as a battery-powered power source.In this circuit, a reference potential generating circuit incorporating FET into the electrical circuit is used for capacitor charging, and the circuit is shut off during music playback to prevent power supply noise from entering. This cuts out the intrusion of power supply noise. A rotating resistor type volume is used for the volume.In this volume, a new structure is adopted in which the brush is fixed and the resistor is rotated, which is completely opposite to the conventional structure. This reduces the number of dissimilar metal joints that cause sound quality deterioration. In addition, distortion is greatly improved by specially blending finely divided carbon for the resistor. In addition, a zinc die-cast case with a high specific gravity is used to prevent external vibrations from being transmitted to the brush. An R-core transformer is used for the power transformer, reducing leakage flux and achieving excellent regulation. The chassis structure uses THCB (Technics Hybrid Construction Base), and the vibration-proof design of a copper-plated steel bottom chassis and a steel chassis sandwiching a hard rubber base provides excellent vibration damping characteristics. To reduce contact resistance, gold-plated input/output terminals and gold-clad contact relays are used. It also features high-precision balanced input and output terminals. The electrolytic capacitors are MASTER series high-quality aluminum electrolytic capacitors, which have improved mechanical characteristics by using a special vibration-damping aluminum case. In addition, newly developed non-inductive high-quality resistors are used for the resistors. The unit is equipped with a phono equalizer amplifier that is compatible with MM/MC cartridges. A system remote control is included that can also operate Technics CD player, tuner, and cassette deck.
