This unit is the NR-1, a ribbon-type cartridge from Nagaoka Jeweltone.
It comes with the genuine stylus guard, a Jewel Tone brand Al-703J headshell, and Audio-Technica LC-OFC lead wires AT625.
Although referred to as "ribbon-type," it is technically classified as an air-core, direct-coupled MC (moving coil) cartridge.
Its generating mechanism is similar to that of the Westrex 10A or Satin models; however, while those generate electricity by vibrating fine coils, the NR-1 generates electricity by vibrating a wide, flat copper strip instead of a coil.
It is called "ribbon-type" because this flat, wide, and thin copper strip resembles a ribbon.
Unlike standard coils, which consist of fine wire wound multiple times, this design results in characteristics of low impedance and low output voltage.
Therefore, to achieve optimal performance, a high-quality MC step-up transformer compatible with low impedance, or a low-noise MC head amp (pre-preamp) or phono equalizer, is required.
As with other direct-coupled cartridges, the clearance between the cartridge and the record surface is minimal; therefore, please ensure the tonearm height is adjusted precisely.
Due to its structural characteristics, mistracking (such as the stylus skipping out of the groove or distortion) may occur when playing records with grooves containing high-amplitude signals. While increasing the tracking force can mitigate the issue to some extent, it cannot be completely prevented.
As is the case with many direct-coupled cartridges, this unit tends to be sensitive to the specific records being played. Please understand in advance that this is not an all-purpose cartridge.
