LV-103
Commentary

This is a hybrid pre-main amplifier that uses a vacuum tube with excellent musical reproduction power and a Bridd circuit using high-speed and high-power MOS FET.

FET in the first stage, 3-pole tube in the pre-driver stage, and MOS FET in the last stage are applied, and voltage amplification is carried out in all stages to suppress interference distortion caused by current amplification.

The S. T. A. R. circuit is adopted in which all lines are directly connected from the reference point to each point without sharing the power supply line and ground line in the circuit, and the silence and nuance between sounds are reproduced as transparent as possible.
