The stylus is a wear item with a typical service life of approximately 300-400 hours. Normal wear may be accelerated by improper handling, excessive tracking force, low-quality records, or unstable turntable surfaces. As the stylus tip's radius of curvature increases over time, its ability to accurately track high-frequency signals diminishes. When o details decrease, high frequencies become less clear and sound quality becomes duller, indicating it may be time to replace the stylus. The stylus is constructed from high-quality materials to enhance durability and maintain consistent sound performance. Output voltage: 4.2 mV. Frequency response: 20 Hz - 20 kHz. Channel balance: 1.5 dB. Stylus type: Highly polished 0.0006 inch conical diamond. Stylus construction: Bonded round shank. Color: White. Material: Plastic. Package includes: 1 x Turntable Stylus. Other items not included. Note: Lighting and display differences may cause slight color variations between the image and the actual item. Measurement tolerance: +/- 1-3 cm.
