Description
 
Stereo power amplifier developed as an Answer to the task how far a tone quality can be refined while securing the Oide power in which all kinds of speaker might be driven.

The large-sized toroidal transformer and mass capacitor of 1.2kVA are adopted as a power-source part per one side channel, and capacity to send out the pulse of 45V by a large current called per single-sided channel 30A at a peek is realized.

The interior serves as a perfect monophonic construction, and selects carefully and uses the highly precise thing for using parts.
The cable made from a pure copper of a very thick is used especially for an internal wiring.

A dumping factor can change to three steps of NOM/LOW/HIGH with a changeover switch on the back, and the adaptivity to the speaker is improved more.
