About the S7

The Simon Yorke S-7 turntable is a precision analogue disc transcription system handcrafted in County Durham. It features a platter machined to micron accuracy from a 30mm slab of non-magnetic stainless steel, weighing over 11 kg, acting as a perfectly balanced flywheel. The turntable weighs approximately 48 kg in total, resting on a 30mm thick slab of Italian slate for stability. The main chassis is a 185mm diameter stainless steel disc housing the bearing and supporting one or two armboards. It uses an AC synchronous motor connected by two drive belts, isolating the turntable from motor vibrations. The S-7 supports speeds of 33.3, 45, and 78 rpm, with options for fixed speed or extended speed ranges when modified. It is known for its exceptional build quality, precision, and sound performance, having been chosen by the Library of Congress for archival disc transfers. The design includes features such as a removable spindle collar to accommodate off-center discs and a modular tonearm system. The turntable requires a serious, heavy stand due to its weight and construction. It is considered a machine tool in service to music, built to last decades with minimal maintenance.
