Fidelity Research Transformer
The FRT-3G
Universal toroidal step-up transformer for use with Moving Coil(MC) cartridges. Three selectable input impedance positions, Low(3-10 Ohm), High(15-40 Ohm), and MM(bypass). Compatibility with almost every MC cartridge sold. Solid output cable. The permalloy core material eliminates the Barkhausen effect. The solid ring-shaped core improves transient response and reduces non-linear distortion typically found in non-toroidal core transformers at low volume levels due to poor hysteresis characteristics. This toroidal core also results in extremely low magnetic flux leakage values to assure high efficiency.
