RS-30EQ Phono Preamplifier equipped with CR-Type, Non-NFB phono equalizer

RS-30EQ picture No.1

RS-30EQ is equipped with the CR-type equalizer based on GE(General Electric/USA) 12AT7 authorized by J.A.N.(Joint Army & Navy) standard of the US Army, and can reproduce a very high quality and clear sound without adding any NFB.
To avoid compromising sound quality using the NFB type, one of the solutions we adapted to completely protect the sensitive CR type equalizer was to originally develop for RS-30EQ a high quality "Orient-Core" power transformer perfectly shielded to shut-down hum noise from the transformer perfectly.
We have also selected the finest available high-end audio components to keep the deflection of the RIAA curve below +/-0.2%.
