Quartz-Locked Fully-Automatic Turntable (1982) Tested, Japanese version 100v, I include a power converter to 220v (small compact), new needle, the device is serviced and ready for use, see the photos for condition. The vinyl record player has been upgraded with the addition of ground wires and RCA plugs. The JVC Victor QL-Y55F attacks unwanted resonance in a new way, actively rather than passively, by means of a sophisticated electro-servo tonearm. This remarkable tonearm also allows hands off left-right and up-down cueing, and in play adjustment of tracking force, anti-skating and damping. Matched to this tonearm is an extraordinarily accurate platter drive system. Speed accuracy is 30 times more accurate thanks to the double servo quartz speed detection system that monitors and adjusts platter speeds with electronic precision. Features of the QL-Y55F include: A tapered, low mass straight arm Resonance free solid cabinet TH (Tracing hold) for high arm sensitivity Low-centre of gravity insulators for high cabinet stability SPECS: Motor: coreless DC servo motor Drive system: direct drive Speed detection system: integrated frequency generator Servo system: double servo quartz Wow and flutter: 0.015% WRMS Signal to noise ratio: 78dB Speed deviation: 0.002% Platter: 2kg 308mm diecast aluminium Tonearm: dynamically balanced electronic servo controlled arm Effective length: 254mm Overhang: 15mm Tracking force: 0 to 3g Cartridge weight range: 3.5 to 9.5g Operation mode: fully automatic Dimensions: 495 x 195 x 405mm Weight: 12kg
