About the RS-30EQ

The Leben RS-30EQ is a tubed phono preamplifier that utilizes a CR-type equalizer based on General Electric's 12AT7 tubes, authorized by the Joint Army and Navy (JAN) standard. It features a tube complement of two JAN 12AT7A and one 6X5GT, offering a gain of 23.5dB. The device maintains a precise RIAA curve deviation of less than +/-0.2% and includes a high-quality 'Orient-Core' power transformer to minimize hum noise. It has an input impedance of 47kOhm, a maximum input of 400mV at 2kHz, and an output voltage of 175mV. The RS-30EQ consumes 17W of power and weighs 6.0 kg, with dimensions of 340mm x 140mm x 240mm.
