Ortofon 2M 78 Verso

The Ortofon 2M 78 Verso cartridge for shellac can be easily mounted from below on old Thorens Haedshells. It has a stereo generator that only reads the side fonts of the record grooves. With two separate windings, it generates two identical signals for the right and left channels and can thus be used in two-channel systems without restrictions.

With the Ortofon 2M 78 cartridge for shellac records, you can experience shellac records from around 1939 onwards in a new way.
