This transformer is designed to match low impedance moving coil phono cartridges with 47 kiloohms RIAA preamps. It is ideal for improving the signal-to-noise ratio of vacuum tube preamps. 60 dB nested double magnetic shielding is standard. See alternate data sheets for use with other impedance ranges.
Adds 17.5 dB of low noise, low distortion gain to RIAA preamps
Wide bandwidth: -3 dB at 0.4 Hz and 100 kHz
Deviation from Linear Phase 1° typical at 20 Hz
Transformer Noise Figure only 1.1 dB @ 45 ohms, 1.7 dB @ 27 ohms
