Commentary
Hybrid pre-main amplifier introduced as the first product of the new concept component "Bridge series" which combines advanced technology and traditional materials
It uses a vacuum tube with excellent musical characteristics and an FET with power and characteristics.
FET is used in the first stage, 3-pole tube is used in the pre-driver stage where high voltage resistance and linearity are required, and MOS FET is used in the last stage.
In order to eliminate current distortion, a voltage-controlled amplifier circuit is employed in all stages to prevent interference distortion caused by current amplification.
S. T. A. R. circuits are used to eliminate interference between circuit blocks and signal paths.
In this circuit, the sharing of the ground line and power supply line, which was often done in the conventional amplifier circuit, is abolished, and all lines are drawn directly from the reference point to each circuit block and signal path to realize smooth signal flow.
It is also equipped with an input section for video signals to support AV equipment.
