Ortofon no longer makes Pmount cartridges; you will receive a N.O.S. or used cartridge that has been professionally tested/recertified by our senior tech along with your brand new genuine Ortofon Stylus 20.
The OMP 20 was a Pmount magnetic cartridge (MM) with an NUDE (natural diamond) elliptical shaped stylus that is a great foray into the world of HiFi, based off of the proven and time-tested OM series. The OMP 20 was designed for use with P-Mount (T4P) type tonearms as generally found on linear tracking type turntables.
