The DQX-500 is a direct result of our many years of experience in producing turntables and we think that it gives full rein both to this experience and to the basic design that we adopt for out models. Brand new head shell installed. Recreated balance weight +/-99-Grams Perfect working Ortofon MC10 Cartridge, MC! DQX-500 FEATURES: 350 mm diameter platter with 600 kg×cm² moment of inertia and quartz lock servo PLL DC motor. The platter used for the DQX-500 features an extremely high moment of inertia of 600 kg×cm², and this helps suppress fluctuations in the pulsive mechanical amplitude caused by the sound grooves on the record. Stand-by lamp for easy rated speed checks . The quartz lock servo PLL system provides a rotational speed with no deviation from the rated 33-1/3 rpm and 45 rpm speeds. There is no need for a strobe and so this has been abandoned in favor of a simple design.
