Question about Pioneer Audio Players & Recorders
If your Pioneer PL 640 turntable is experiencing variations in speed, there are a few potential causes to consider. Here are some steps you can take to troubleshoot and fix the issue: Check the belt: The belt on the turntable may have become stretched or worn, which can cause variations in speed. Inspect the belt for any signs of damage or wear, and replace it if necessary. Check the platter: The platter may be dirty or have accumulated debris, which can cause it to spin unevenly. Remove the platter and clean it thoroughly, and make sure it is seated correctly on the spindle. Check the motor: The motor may be malfunctioning or dirty, which can cause variations in speed. Remove the motor and clean it, and check it for any signs of damage or wear. If necessary, replace the motor. Check the pitch control: The pitch control on the turntable may be dirty or malfunctioning, which can cause variations in speed. Clean the pitch control and make sure it is working correctly. Check the power supply: The power supply may be providing insufficient power to the turntable, which can cause variations in speed. Check the voltage output of the power supply, and make sure it is within the manufacturer's recommended range. If none of these steps resolves the issue, you may need to take your turntable to a professional repair technician for further diagnosis and repair.
