The sole, pure Japan-born semi-conductor developed by Dr. J. Nishizawa, ex-president of Tohoku University and world-known authority of metal engineering which utilises induction effects of statics makes it possible to treat large current under low electricity consumption : Its reduction capability of channel resistance to the absolute minimum assures low inner resistance, high speed and low energy loss, thus realising signal amplification totally faithful to signal wave-forms.
Inherent characteristics common to those of direct-heated triode valves help lower odd numbered THD.
Equal-μ characteristics offering superb linearity reduce voltage amplification distortion.
Large voltage amplification ratio ensures low-voltage operation.
Excellent treble characteristics extend gain bandwidth, thus lowering phase distortion.
