Title
"Re-cap" and electrically overhaul a direct drive turntable to fix speed issues.
Introduction
Direct drive turntables use sophisticated circuitry to control their brush-less DC motors. Over time these units can develop erratic speed issues due to leaky electrolytic capacitors, dirty contacts and potentiometers, cracked PCB solder joints, or faulty transistors and ICs.
In most cases, speed issues can be fixed by cleaning potentiometers and switches. If this does not resolve your issue and your unit is over 20 years old, you may need to “re-cap” it, which entails replacing old and leaky electrolytic capacitors with new ones of the same value.
If the speed issues still persist after cleaning contacts, replacing capacitors, and re-flowing cracked solder joints, you may have a faulty transistor or IC. This guide shows you how you can check and replace these parts as well.
