Tone arm AMG 12J2
Dear music-lover,
thank you for your vote of confidence by choosing the AMG tone arm for playing your records.
Technical description
The tone arm 12J2 has been developed in a completely new patented principle of engineering.
Starting out from a standard tone arm with horizontal and vertical axles and the bearing play caused
by the principle of design, we have totally eliminated the play in the horizontal axis by replacing it with
two 0.5 mm thick spring steel wires. This also enables a direct acoustic coupling which exactly draws
from your record what is truly on it. This principle is also used in the rotor heads of helicopters
replacing the standard bearings and their play.
The vertical axle is made of hardened tool steel and precision ground to a backlash-free fit with a
needle roller bearing. The axles are maintenance free and never need to be adjusted.
The antiskating system is also integrated in the bearing case. In the upper rim of the arm shaft you
see two M 1.6 hexagon socket screws. By loosening them you can move them up and down and
adjust the antiskating force.
All materials we use are stainless steel, tool steel, spring steel, anodized aluminum in aircraft quality.
The arm tube locking lever is plastic molded, the coupling attenuation sleeve in the counter weight is
Teflon and the insert in the arm tube rest at the lift is of silicone.
Preparation for installation
Take the tone arm out of the wooden box and place it on a soft rag on a level surface. Please check
that the arm tube is locked by the locking lever. Insert the audio cartridge into the head shell to a
preliminary position and slide the color coded female connectors on to the related pins at the cartridge.
Now start with the final adjustment.

Drilling the mounting bore
Please mark out as precise as possible the distance from pivot to turntable center of 291.4 mm.
Drill a bore in your plinth or arm board at exactly this distance. You may use the mounting bushing as
a template to drill the bores for the three fastening screws. The screws are metric M 3. For a wooden
plinth use appropriate screws for wood.. Insert the mounting bushing so as the locking screw for the
tone arm shaft is easy accessible from the right.
If you do not have a drill press or better a milling machine, please see a machine shop.
The 12J2 tone arm is available in three different variations concerning his connection.
With a SME connector in the tone arm shaft were you may direct connect your audio cable
With a SME connector in the tone arm shaft and a female SME connector you may make your own
cable with.
With flying leads, which you have to solder to cinch or XLR connectors.
