A belt-drive, fully automatic turntable built as an affordable entry-level option during vinyl's decline.

Overview

The Technics SL-BD20 is a belt-drive, fully automatic turntable made from 1986 to 1999. It was sold as a budget entry-level model. It has auto-return and auto-stop, two speeds (33 1/3 and 45 RPM), a DC motor with servo control, and support for P-mount cartridges.

Market

Units turn up priced as low as $58 for parts-only models that need a belt replacement. Working units are listed around $100. Common problems are hum, auto-return malfunctions, grinding noises, and tonearm trouble linked to degraded silicone damping fluid. Belt replacement is a frequent maintenance job.
