The Leben RS-30EQ MM Phono Preamplifier is equipped with a CR-type equalizer based on the General Electric (USA) 12AT7 tube, authorized by the J.A.N. (Joint Army & Navy) standard of the US Army, and can reproduce very high-quality and clear sound without adding any negative feedback (NFB). To avoid compromising sound quality via the NFB type, Leben developed a high-quality “Orient-Core” power transformer for the RS-30EQ. This transformer is perfectly shielded to eliminate hum noise.

Leben have also selected the finest available high-end audio components to keep the deflection of the RIAA curve below +/-0.2%.
