ORTOFON OMP 20 Style T4P P-mount Phono Cartridge

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.

NOTES:

• Ortofon has discontinued their Pmount line. They no longer support T4P.
• Current offerings are from various buyouts. 
• Depending on availability, you may receive a black or tan/off white Ortofon TM, OMP, N120 or OMT cartridge that may be N.O.S. or used but always tested.
• Some of the genuine packaging is "shop worn" meaning it's been bouncing around drawers for decades.
• May arrive in a worn Ortofon box or repackaged in our own protective box.
• We are installing a brand new current production Genuine Ortofon Stylus 20. You will not receive a N.O.S. stylus.
• All will be professionally inspected both visually and electrically under the watchful eye of our senior electronics technician.

OPTIONS:
OMT = about 690 ohms
OMP = about 700 ohms
No further info could be found as of press time about why Ortofon labeled some of their T4P OM Pmount series cartridges OMT instead of OMP. The bodies are physically exactly the same. It may have been a private label offering.
