The pure Class-A Integrated Amplifier which adopted
the original custom-made part and was developed.
The mass power
transformer which heightens not only the static characteristic but dynamic
energy supply capacity is carried in the power-source part. Furthermore, the
original custom-made part is constituted in the regulator circuitry or the
i"The overly large-sized rotary switch type ultimate Attenuator (the
Lux developed uniquely)" is carried in the sound-volume control fraction.
Based on 32 contact rotary switch by a glass epoxy gilding
substrate, it has a structure which mounted one non-magnetic-material resistor [
one piece ], and the threshold on the tone quality by the stray current and the
contact quality of the material of a slide part of having occurred in the
general succession good transformation volume is improved.
Furthermore, it stored in the shielding case by aluminum die-casting and
extrusion material, and the influence on a tone quality is eliminated.
A circuit design called
input selector + power amplifier is made into the concept, and simple-ization of
the signal path from an input terminal to a speaker termination is attained.
Leading about of a signal path is stopped to the minimum by adopting a
golden contact relay as the change of the input which amounts to ten lines, and
performing an input switching in the location close to an input terminal.
Moreover, in order to switch this relay circuit not only including the hot side
but including the grounding side, except a address signal circuitry, it was
separated completely and has realized the pure signal path.
Furthermore, thorough simple-ization, such as also eliminating a speaker
A/B change and a headphone jack, is attained.
Highly efficient parts, such as a gilding cap
non-magnetic-material resistor, a Copper-foil styrene capacitor, a pure Focus
type electrolytic capacitor, and a high purity copper cable, are adopted.
Special FRP containing ceramic of a large mass is adopted as a bottom
chassis by high rigidity, and the influence of an extraneous vibration or an
internal oscillation is reduced by the insulator of a five-point setting.
The tone control which thought the phase as important is adopted and a
natural correction is possible.
