Commentary
This pre-main amplifier has been simplified and shortened thoroughly and has a simple configuration.
In the power amplifier section, the final stage is composed of discrete power transistors with sufficient margin, and the power supply section is strengthened to improve the low impedance drive capability.
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.
