Experiencing your Pioneer turntable repeating the same section of a record can be frustrating for any vinyl enthusiast. This common issue often stems from a few key mechanical factors, typically related to the tonearm’s movement and the automatic return system. Before assuming a major malfunction, there are a couple of straightforward checks and fixes you can attempt to restore your turntable’s smooth operation and enjoy uninterrupted listening.
Initial Checks: Tracking Force Adjustment
The first and easiest step in diagnosing a repeating record issue is to verify the tracking force of your cartridge. The tracking force is the pressure exerted by the stylus on the vinyl record, and it’s crucial for proper playback. If the tracking force is set too light, the stylus might not track correctly in the record groove, leading to skipping or repeating.
Most Pioneer turntables, including models like the PL-200Z, allow for tracking force adjustment. Consult your turntable’s manual or the specifications for your specific cartridge to determine the recommended tracking force range. Using a tracking force gauge is advisable for accurate measurement, but you can also use the markings on the tonearm counterweight as a starting point. Adjust the counterweight until the tracking force is within the recommended range. After adjustment, play a record to see if the repeating issue has been resolved. Often, simply setting the correct tracking force is enough to solve this problem.
Deeper Dive: Cleaning the Trip Pawls
If adjusting the tracking force doesn’t solve the repeating issue, the problem might lie within the turntable’s automatic mechanism, specifically with the trip pawls located on the main cam gear. These small components are essential for the automatic return of the tonearm at the end of a record. Over time, old grease can harden and cause these trip pawls to become sticky or stuck, hindering their free movement. When the trip pawls are not functioning correctly, the tonearm may not advance smoothly across the record, leading to repeated sections of play.
To address this, you may need to access and clean the trip pawls. On some Pioneer turntables, the main cam gear and trip pawls are accessible by simply removing the platter. In other models, accessing these components may require disassembling part of the turntable mechanism.
Here’s a general guide to cleaning the trip pawls:
-
Locate the Cam Gear and Trip Pawls: After removing the platter, carefully examine the mechanism. Look for a large gear (the main cam gear) and small levers or pawls that move around it (the trip pawls). Refer to the image below for a visual guide.
-
Gentle Cleaning: Dip a small piece of lint-free cloth or rag in isopropyl alcohol. Carefully work the alcohol-dampened cloth around the trip pawls, focusing on the areas where they pivot and make contact with the cam gear. The goal is to dissolve and remove any old, hardened grease.
-
Allow to Dry: Let the alcohol evaporate completely. Do not apply any new lubricant to the trip pawls, as this can attract dust and eventually lead to the same problem.
-
Reassemble and Test: Reattach the platter and belt if removed. Play a record to test if cleaning the trip pawls has resolved the repeating issue.
Important Cautions:
- Handle with Care: Turntable mechanisms are delicate. Be gentle when cleaning and avoid forcing any parts.
- Seek Professional Help if Unsure: If you are not comfortable disassembling or cleaning turntable mechanisms, it is always best to consult a qualified turntable repair technician.
By systematically checking the tracking force and cleaning the trip pawls, you can often resolve repeating issues and ensure your Pioneer turntable continues to provide enjoyable vinyl playback.
