The SPU Mono CG 65 Di MkII for the reproduction of early 65 µm mono and 78 rpm recordings

The Mono CG 65 Di MkII is an SPU-style moving coil cartridge with a spherical stylus profile. The CG 65 Di MkII offers an authentic method for reproducing these early recordings with a remarkable degree of sonic accuracy, regardless of the materials from which these discs were made.

This cartridge features a 1.5 mV output, making it suitable for use with a wide range of medium-gain moving coil transformers. The Ortofon ST-M25 moving coil transformer was designed exclusively for the SPU Mono CG 25 Di MkII and the SPU Mono CG 65 Di MkII.
