Commentary
A control amplifier developed for low 歪低 noise.
A low-noise FET transistor is used in the first stage of the equalizer circuit, and an IC for the equalizer is used in the second stage to achieve high performance.
The ICL / DC configuration is used in pursuit of sound quality.
Tape dubbing is also possible while enjoying playback from other sources.
