Commentary
This pre-main amplifier is designed for high quality and casual that can be enjoyed from audio to visual.
IC with excellent S/N and distortion characteristics is adopted for the drive stage, and large capacity Pc60W, f is adopted for the final stage.TA power stage using a 20 MHz power transistor is configured.
In order to play characters from all sound sources, the motherboard chassis layout is designed to simplify the circuitry and idealize the layout of parts and wiring.
For sound quality control, we use continuously variable loudness control which also serves as tone control function.
It is characterized by stable operation without degradation of distortion factor observed in general tone circuits.
