Yaqin MS-12B Tube Preamp with MM Phono, Dual Outputs (Trade-in)
Excellent condition with upgraded tubes and power cord. This is not a remote controlled pre. No sales tax.
Features
For use with CD/ DVD or streaming DAC, and vinyl LP's (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 standards 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.
