YAQIN MS-12B PRE-AMP 12AX7 X2 TUBE INTEGRATED W/PHONO
PID# 53192
Description
Features
Able to be applied to CD/ DVD and black lacquer disk phonograph (RIAA)
Amplifier provided with output of hight/low two electric levels, namely (0.7V/0.2V),
so that it is applicable to pure post-stage amplifier and integrated amplifier
Black lacquer pickup amplifier adopts negative-negative feedback typed equalization circuit,
in conformity to RIAA characters with good acoustic quality.
The preceding stage amplifier takes a negative pole output circuit, featuring an advantage
of transmission with low impedance.
Touch typed relay transformation is adopted for signal transformation.
The filament of electron tube refers to DC power supply, So that noise with this amplifier is minimized.
This amplifier is manufactured by using linked capactitance special for import audio
frequency (MKP) as well as filtration electrolyse and quality metal resistance special for import acoustics.
The power supply transformer is made of oxygen-free enameled copper wire and
silicon steel plate special for import acoustics.
