I’ve just serviced a rare Sonab 85S belt-drive turntable. The Sonab 85S is an unusual design, quite nice for a belt-drive deck and very solidly built. The deck should give years more good service, after the work we’ve done here.
The Sonab 85S is a 2-speed, belt-drive turntable with integral tonearm and comes fitted with a moving-magnet cartridge. I have borrowed the following specifications from the Vinyl Engine:
Motor: AC synchronous
Speeds: 33 and 45rpm
Platter: 300mm, 1.2kg
Wow and flutter: 0.08%
Tonearm: static balance type
Stylus pressure: 0.5 to 3g
Cartridge weight: 5 to 12g
Cartridge: Ortofon F 15 EO
Stylus: 18 x 8um elliptical diamond
Frequency response: 20 to 20,000Hz
Recommended tracking force: 1.5g
Dimensions: 440 x 370 x 160mm
This old girl needed a new belt, some cleaning and lubrication and a careful setup of the tonearm and cartridge. Once these jobs were done she worked perfectly and sounded really nice!
