Ortofon SPU Mono GM MkII for playback of early mono records

The SPU Mono GM MKII is a high output Moving Coil cartridge a 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 remarkable level of sonic accuracy, and its high output negates the need for a moving coil transformer.

Ortofon’s SPU cartridges continue the tradition of the first ever Moving Coil cartridges as originally engineered by Mr. Robert Gudmandsen and produced by Ortofon in the late 1950s. Praised for their refined linearity and full body, these cartridges have remained a favourite throughout the years, both for modern and vintage high-end applications. This year we decided to give our SPU fans around the world an opportunity to get a collection of the four most famous SPUs, each of them being a very special collector's item.
