SPU Mono GM MKII 

The SPU Mono GM MkII is a high output Moving Coil cartridge with a spherical stylus profile for the playback of early 25µm mono recordings.

The SPU Mono GM MkII provides an authentic method of playing back these early vinyl recordings with a remarkable level of sonic accuracy, and its high output negates the need for a moving coil transformer.
