Fidelity Research Transformer
This step-up transformer is designed for use with MC cartridges having an impedance of no more than 10 ohms. Along with simplifying and rationalizing the circuit design, Fidelity Research have also been very careful in the selection of each circuit component used.
Designed and built specifically for use with the FR-7 and other very low load impedance MC cartridges, the FRT-5 core material is a new type of permalloy, specially processed to obtain virtually ideal performance characteristics. The toroidal core design offers the best possible response available with today's most advanced technology(1980). A front panel selector lets you switch between three cartridge/tonearm inputs.
