A bit more detailed information: SKALA

Although the plastic base is pretty much flush with the metal blade where contact is made with the headshell, the plastic will compress under pressure, while the blade will not. This allows a limited degree of azimuth adjustment to be made by the careful application of different amounts of torque to left and right mounting screws. Extreme care should be taken to tighten both mounting screws gradually and evenly, a little at a time. Over cranking one screw and then doing the same for the other could result in an unintentional change to the azimuth. The drilled holes in the plastic body are themselves lined with metal jackets to receive the mounting screws securely.

The magnetic system in the Skala is the same non-polepiece twin-disc direct-magnet system also used in most other LYRA models. However the body shape has been even more heavily carved away in the area of the magnet than any previous model– even more than on the Titan. This results in fewer eddy currents in a very sensitive area of the cartridge. New elements are a new non-conductive and non-magnetic front magnet carrier, a new cantilever system, a new output pin design, and a new output-pin carrier. The stylus guard is the same grooved slide-on type that has proven so successful on the other LYRA models.
