The true nature of an audio is pursued and they are an improvement and a large wide-range DC amplifier stream composition of a play frequency band about a physical characteristic in a modification of the nakedness property of amplifier.

DC power amplifier part which adopted the newly developed Dual FET, the peculiar current mirror circuitry, etc.

The high-order-accuracy 8 stone stream-composition equalizer part the distortion and whose SN ratio improved.

An independent large-sized power transformer and a power circuit are adopted as a right-and-left channel.

The protection network of a hi-reliability design

A Subsonic Filter, a loudness switchpoint

Isolation of a pre-main, an AC-DC main-amplifier input terminal.

A Dual-unit Detent volume with little error

A unique tapes play functionality.
