60s year Fidelity Research FRT-3 step up transformer for almost MC cartridges. There is 2 input for both MC low impedance and high impedance cartridges. Sound is perfect ! can be matching with almost cartridges.Step-up transformer for MC using a toroidal core. By developing and adopting a ring-shaped toroidal core, the nonlinear distortion and noise component resulting from the hysteresis curve and Barkhausen effect are eliminated.Primary impedance 10?, 30?, PASS (switching) Secondary impedance 12k? Load impedance 47k? to 50k? Step-up ratio 10?: 31dB (36 times) 30?: 26dB (21 times) Frequency band 20Hz-30kHz Distortion rate Output 2Vrms is within the measurement error and cannot be determined Dimensions Width 64x Height 64x Depth 105mm Please check business term before bidding on my item /////////////////////////////// NOTE: 1.
