This pre-main amplifier is dedicated to pure music playback.
The power supply uses a triple-diffused transistor with excellent high-current drive capability to achieve high power and high saturation.
In order to take advantage of the inherent characteristics of CDs, the S/N ratio has been improved by adopting a direct coupling configuration using a low-noise FET for the high-level input stage where CDs are input.
In addition, a CD direct switch is mounted to enable high-speed signal transmission at a higher S/N ratio.
The input signal of the CD-1 jumps in the selector and balance, is directly connected from the volume to the flat amplifier, and is reproduced in the shortest path.
The phono input can be switched between the MM position and the MC position using the selector.
Equipped with a copy switch that allows one touch dubbing of tapes 1 → 2.
Equipped with a speaker selector that can turn on / off the speaker output 1/2 independently.
OFC (oxygen-free copper) wire is used for main wiring, and gold plated terminals are used for CD-1/2 and phono inputs.
In addition, the parts used are selected through strict hearing, such as using copper plated screws for all the screws.
