| Notes | Micro Seiki BL-91
2-Speed Belt-Drive Turntable (1979-1983)
Description
Features a massive, thick, 12.2 inch platter, employing special alloy bearings machined and polished with techniques usually reserved for turbojet engines.
Micro Seiki engineers devised an exclusive oil-bath damping system to support the entire rotating assembly in complete isolation from all mechanical resonances.
A precision-ground drive belt connects the rotating assembly to the brushless, servo-controlled motor with total isolation from motor generated vibration.
In fact, the BL-91 (L) is probably the smoothest, most vibration-free device of its kind ever built.
