Commentary
This pre-main amplifier has been simplified and shortened thoroughly and has a simple configuration.
The amplifier is pursued in an orthodox way, and pure transmission is achieved by suppressing interference between each part.
The pure signal ground line is used so that the ripple of the AC power supply and various noise components do not adversely affect the audio signal by allowing only pure signal to flow through the main ground line.
Logical flow construction is employed to minimize the signal path.
In addition, the printed circuit board is also fixed soft so that it is less susceptible to vibration.
It is equipped with a source direct circuit so that you can bypass these circuits when you do not use tone control, balance control or subsonic circuits.
It is equipped with a loudness control and MM phono equalizer.
