This tip is a spherical diamond of R 65 µm, roughly three and a half times the radius of the 2M Mono’s R 18 µm, sized to ride the groove walls of a shellac disc properly.\u003c\/p\u003e\n\u003cp\u003eIt is the replacement stylus for the 2M 78, but the more interesting use is as a second stylus. The 2M Mono and 2M 78 share a body, so if you already own a 2M Mono this part alone adds 78rpm capability, and switching between shellac and mono LPs becomes a few seconds of work with no realignment. For a collector with both formats it is a considerably better buy than a second cartridge.\u003c\/p\u003e\n\u003cp\u003eOne caveat we will offer ourselves, since Ortofon does not: 78s were cut to a range of pre-RIAA equalisation curves, and a standard RIAA phono stage will replay them with a noticeably wrong tonal balance. This stylus solves the mechanical half of the problem. The equalisation is a separate question, and one worth a conversation if you are putting a shellac setup together.\u003c\/p\u003e\n\u003ch4\u003eFeatures\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eSpherical diamond, R 65 µm, sized for the coarse groove of shellac 78s\u003c\/li\u003e\n\u003cli\u003eReplacement stylus for the 2M 78\u003c\/li\u003e\n\u003cli\u003eAlso fits the 2M Mono body — adds 78rpm playback to a cartridge you already own\u003c\/li\u003e\n\u003cli\u003eSlides on and off — no realignment needed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Replacement stylus unit for Ortofon 2M 78\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStylus Type:\u003c\/strong\u003e Spherical.
