The Integrated Amplifier developed in response to
the thought of a fan fascinated with the sound of the thermionic tube against
the background of an old tradition.
KT-88 is adopted as an output tube as a key device of power amplifier.
A power amplifier part is clear in the
reference point of an amplification, and the Williamson circuitry without くせ
peculiar to low-pass is used for it.
The inversion signal was formed by
little PK splitting of the tone-quality failure, output-tube KT-88 was used by
the push pull, and NFB in the total was minimized and has realized the music
play which does not spoil a musical feeling of a lively motion.
which determined the validation of the Lux as a transformer manufacture is
adopted as an output transformer.
Orient core material was used and very
little straight tone quality of the phase rotation has been obtained by this
transformer finished by a skillful technician's manual labor based on a
splitting volume original with OY type.
A preamplifier part supplies the design know-how cultivated by then, and is designed.
Moreover, the circuitry by the thermionic tube is adopted also as the tone control circuit which is an attached circuitry.
The input system also supports combination with various digital
equipment while it builds in the high-definition phone equalizer circuitry
excellent in the S/N ratio in addition to four line inputs and pulls out the
charm of an analog disk to the maximum extent.
Leakage flux is put into
practice and eliminated by putting into practice also among the measure against
a noise, and the main unit of a transformer being filled up with fixed material
on a severe shielding, and also storing in iron cases.
property of a circuitry is fully pulled out, and in order to accomplish a design
concept, many custom-made parts are adopted as SQ-88.
type high-quality sound volume was adopted as volume control, and the
custom-made part with abundant amount of information is adopted by the low-noise
which added the enhancement also to the electrolytic capacitor or the molded
resistor for exclusive use.
Moreover, the adopted thermionic tube sorted out
only what cleared the severe quality testing by Lux criteria, and has acquired
the high robustness for an original charm of the thermionic tube with the high
