How to Change the Stylus on an Audio-Technica AT-LP120 USB Turntable

When it comes to enjoying vinyl records, a good turntable with a properly aligned stylus is essential for optimal sound quality. Over time, styluses can become bent or worn, affecting the overall performance of the turntable. In this article, we will guide you through the process of changing the stylus on an Audio-Technica AT-LP120 USB turntable, ensuring that you can continue to enjoy your favorite records with pristine sound.

1. Introduction

The stylus, also known as a needle, is a crucial component of a turntable's cartridge. It comes into contact with the grooves of the vinyl record, translating the physical grooves into electrical signals that produce sound. Over time, styluses can become damaged or worn out, resulting in skipping, distortion, or poor audio quality. In such cases, replacing the stylus is necessary to restore the optimal performance of the turntable.

2. Reasons for Changing the Stylus

There are several reasons why you might need to change the stylus on your turntable. Common reasons include:

• Bent or damaged stylus: If you notice that your stylus is bent or damaged, it is important to replace it as it can cause skipping or even damage your records.

• Worn-out stylus: With prolonged use, styluses can wear out, resulting in a decrease in sound quality. If you notice distortion or lack of detail in the playback, it might be time to replace the stylus.

3. Purchasing a Replacement Stylus

Before replacing the stylus, you need to purchase a compatible replacement. Audio-Technica offers a range of replacement styli for their AT-LP120 USB turntable. It is recommended to choose a stylus that matches the specifications of the original, ensuring compatibility and optimal performance. You can find replacement styluses online or at audio equipment stores. Ensure to purchase from a reputable seller to guarantee authenticity.

Once you have obtained the replacement stylus, you are ready to begin the installation process.

4. Removing the Old Stylus

To remove the old stylus, you will need to take a careful approach. Start by turning off the turntable and lifting the protective cover. Locate the cartridge, which is the rectangular component that holds the stylus. Hold the cartridge firmly and twist it counterclockwise to remove it from the turntable. Be gentle and ensure not to damage any other components during this process.

Once the cartridge is removed, you will see the stylus attached to the front. Inspect the stylus for any signs of damage. If it appears bent, worn, or damaged in any way, it is time for a replacement.

5. Installing the New Stylus

With the old stylus removed, it is time to install the new one. Take the replacement stylus and position it correctly in the slot where the old stylus was attached. Ensure that it fits securely and aligns properly with the cartridge. Apply gentle pressure to lock it into place.

Tighten the cartridge back onto the turntable by twisting it clockwise. Make sure it is securely fastened to prevent any movement during playback.

6. Checking the Alignment

After installing the new stylus, it is essential to check the alignment to ensure optimal performance. Proper alignment ensures the stylus sits correctly in the grooves of the vinyl record, maximizing sound quality and reducing wear on the stylus and records.

To check the alignment, you can use a cartridge head shell adjustment page. Printing out a page with alignment guides can help you accurately align the stylus. The page should include dots and measurement points to assist in the alignment process.

7. Using the Cartridge Head Shell Adjustment Page

Print out a cartridge head shell adjustment page, making sure to print it at 100% scale for accurate measurements. Verify that the dots and measurements align with the specifications provided. You can use a digital caliper to confirm the measurements and ensure they match those indicated on the page.

8. Punching the Hole for Alignment

To align the stylus properly, you may need to punch a hole on the adjustment page. As an alternative to a hole punch, you can use an X-Acto knife and a block of wood. Starting from the edge of the page, carefully cut towards the center to create a hole that matches the specifications of the cartridge.

9. Applying Packing Tape for Smooth Surface

To provide a smooth surface for the stylus to rest on, cover the dots on the alignment page with packing tape. This prevents the stylus from catching on the paper and ensures a smooth tracking surface. Use enough tape to cover the dots securely.

10. Checking Alignment Again

After applying the packing tape, place the alignment page on the turntable and remove the protective cover. Lower the tonearm onto the alignment page, ensuring that the stylus rests on the tape-covered dots. Check that the stylus is aligned perfectly with the dots using a magnifying glass if needed. Make any necessary adjustments to the screws on the cartridge to ensure proper alignment.

11. Adjusting the Screws for Alignment

If you find that the stylus is not aligned correctly, use a screwdriver to loosen the screws on the cartridge. Carefully adjust the position of the cartridge until the stylus aligns perfectly with the dots. Tighten the screws once the alignment is achieved.

12. Checking the Tracking Force

Tracking force refers to the downward pressure exerted by the stylus on the record. It is essential to set the tracking force within the recommended range to prevent wear on the stylus and records. Most AT-LP120 USB turntables have a tracking force ranging from 1.5 to 2.5 grams, with 2.0 grams being the standard setting.

13. Using a Scale to Measure the Tracking Force

To check the tracking force, you can use a scale designed for measuring such forces. Place the scale under the tonearm and lower it until the stylus lands on the scale. Read the measurement displayed on the scale. It should be within the recommended range.

14. Adjusting the Balance as Required

If the tracking force is not within the recommended range, you may need to adjust the balance to achieve the desired tracking force. Consult the turntable's manual for instructions on how to adjust the balance. Make small adjustments and re-measure the tracking force until it falls within the recommended range.

15. Conclusion

By following these steps, you can successfully change the stylus on your Audio-Technica AT-LP120 USB turntable, ensuring optimal sound quality and prolonging the lifespan of your records. Regularly maintaining and replacing the stylus will provide you with countless hours of enjoyable listening experiences. Remember to always handle the stylus and other delicate components with care to prevent unnecessary damage.
