Description
 
Power amplifier developed by carrying the technology of A-Integrated-Amplifier 10 series.

There were three kinds of variations of "typeIII" not carrying a volume in A-10XXP in "typeI" not carrying a volume, "typeII" with a volume by monophonic (balance input) stereo switching, and a balance / imbalanced [ at balance input loading ] input.

The reserve power source developed in order to obtain perfectly near flattery nature to a dynamic and discontinuous music signal is carried in the power circuit. Moreover, the power-source part corresponding to a low load intensity is realized by adopting a large-sized transformer and mass capacitor.

The twin monophonic construction is altogether adopted as an internal construction until it reaches a transformer, a filter, a capacitor, and the voltage amplification stage. Furthermore, in order to realize high-definition play sound, the monocoque structure which suppressed the natural oscillation is adopted.

In order to bring the ideal of the direct mechanical ground construction which drops an oscillation into a terrestrial mass on heavyweight foot close to a still more perfect thing, an 11kg natural granite is adopted as a top plate.

The sound with a high purity is realized by adopting the thing of highest-class grade as all the used parts.

Real wood is adopted as the front panel and a side panel.
Moreover, various combination was possible for a top plate, the front panel, and a side panel from several kinds of wood.
