Commentary
This is a pre-main amplifier of the Revolver series with duobeta technology.
The power amplifier section is equipped with a duo-beta circuit, and high sound quality is achieved by DC servo which tightens the sound image from the appropriate NFB over the whole band and from the ultra-low band outside the super-band.
Built-in high-gain MC equalizer.
The tone control is equipped with a turnover frequency shift tone control.
The amount of change and the amount of change and the frequency at which it begins to change, making it possible to adjust sound quality naturally and effectively to the audibility.
