Ortofon RMG-309


The ultimate in tone arm efficiency and simplicity of design is expressed in the Ortofon RMG-309.

Precision ball bearing for both vertical and lateral pivots, finely polished, exert only the minimum of inertia.

The ball bearings, gimbal suspension, and base are made of fine Swedish alloys.

The Duralumin arm is rubber damped from the counterweight to reduce resonance to 8Hz - well below audibility.

The counterweight, which controls the stylus force, is spring controlled and can be set for a tracking force of 0 to 7 grams.

The extreme length of the RMG-309 accounts for the very small tracking error which is 0.83 degrees at maximum.

Complete with plug-in cables for ease of installation and elimination of ground loops and hum.

Any other manufactures cartridge may be installed in it's plug-in shell.


Arm length (overall): 16"

Lateral length: 12"

Cartridge offset angle: 15.9 degrees

Tracking force: 0 to 7g

Arm resonance: 8Hz
