ORTOFON Super OM40 OM-40 OM 40 PHONO CARTRIDGE
The OM 40 is the best cartridge within the Super OM series - and some say the best moving magnet cartridge made by Ortofon. With its Fritz Gyger stylus, it resolves the grooves with celestial eloquence, clarity and grace. Its classic Ortofon performance and highly regarded musicality rival the high energy sound of the best 2M series.

ORTOFON STYLUS 78 NEEDLE STYLUS (78 RPM STYLUS)
The Ortofon Stylus 78 needle stylus is the standard 78 RPM replacement stylus for all Ortofon Super OM, OM, OMB, OMP, TM, Concorde phono cartridges. The stylus features a 2.5 mil diamond designed specifically for the correct tracing of the wide grooves of 78 RPM records. It results in minimal groove wear and accurate rendition of voice and music.
A very common misconception is that you can use an LP stylus for playing 78 RPM records. This is one quick and sure way to damage the 78 RPM record grooves. To maintain the playback fidelity of your 78 record, you really need to use a stylus designed for 78 RPM records, otherwise with just a single playing, you could ruin the fidelity of the record grooves. Moreover, the LP stylus is much narrower than the 78 RPM record groove hence the tip will slide to the bottom of the groove where debris has collected for many decades. This results in extraordinarily high-surface noise.
