Commentary
A pre-main amplifier with two power amplifiers.
Two types of amplifiers, low power and high power, are used for the output section, allowing for a wide dynamic range source.
A gain-change-type equalizer amplifier is used.
The structure is designed to minimize interference between each unit, and the signal path is minimized to ensure sound quality.
