Commentary
Pre-main amplifier of Brid series which adopted Duo β circuit.
The Duo β circuit is a technology that first enhances the bare characteristics of the amplifier by simplifying the amplification stage, and then tunes the amplifier by applying an appropriate amount of NFB. It is a system that is simple and easy to bring out the goodness of the material.
NF type is used for tone control.
Built-in equalizer amplifier for MM and MC types.
