Fidelity-Research FR-1mk2
Released in November 1967
¥ 26,000 (around 1978)
Commentary
Based on the basic structure of FR-1, the MC cartridge has improved tracing capability by reducing the vibration system mass.
The vibration system has a strain-free structure that does not contain magnetic materials, such as carefully selected cantilevers and dampers, and elliptical diamond needles that have passed strict inspection.
The replacement needle is compatible among the FR-1 series.
