3. Setup and Installation
Before installing the new needle, ensure your record player is turned off and unplugged from the power source. Handle the stylus carefully to avoid damage.
- Remove Old Needle: Gently grasp the old stylus cartridge and pull it straight out from the tone arm. Some models may require a slight downward or upward angle. Refer to your turntable's specific manual if unsure.
- Identify Stylus Sides: The Durpower 557-DS73 needle is double-sided. One side is marked "LP" for Long Play records (33 1/3 and 45 RPM). The other side, typically unmarked or with a different indicator, is for 78 RPM records. Ensure you orient the correct side for the record type you intend to play.
- Install New Needle: Align the new stylus with the cartridge slot on the tone arm. Gently push it in until it clicks securely into place. Do not force it.
- Verify Installation: Once installed, gently tug on the stylus to ensure it is firmly seated and will not come loose during playback.

4. Operating Instructions
Proper operation ensures optimal sound quality and extends the life of your needle and records.
- Record Placement: Carefully place your record onto the turntable platter.
- Stylus Selection: Ensure the correct stylus side (LP or 78 RPM) is facing down for the type of record you are playing. If your turntable has a flip-over stylus, rotate it accordingly.
- Lowering the Tone Arm: Use the tone arm lift lever to gently lower the stylus onto the outer groove of the record. Avoid dropping the tone arm manually, as this can damage the needle and record.
- Playback: Allow the record to play through. When finished, use the lift lever to raise the tone arm and return it to its rest.
5. Maintenance
Regular maintenance helps preserve sound quality and extends the lifespan of your stylus and records.
- Stylus Cleaning: Periodically clean the stylus tip using a soft brush designed for turntable needles. Brush gently from back to front (away from the cantilever) to remove dust and debris.
- Record Cleaning: Keep your records clean to prevent dust buildup on the stylus. Use a carbon fiber brush or a record cleaning solution.
- Stylus Inspection: Visually inspect the stylus tip regularly for any signs of wear or damage. A worn stylus can damage your records and degrade sound quality.
- Replacement: Replace the stylus when you notice a significant drop in sound quality, distortion, or visible wear on the tip. The lifespan of a diamond stylus varies but typically ranges from 500 to 1000 hours of playback.
