Yamaha YP-511 Direct Drive Record Player Turntable Confirmed Excellent Operation
Yamaha YP-511 Direct Drive Record Player. This record player is designed to reduce the adverse effects of vibration by increasing the weight of key parts. The motor is an 8-pole, 24-slot DC servo motor with high torque. Furthermore, the servo circuit response has been improved to maintain accurate rotation speed even under load fluctuations. The turntable is a 1.6 kg die-cast aluminum turntable, which is dynamically balanced from the mold by precision metalworking technology. This turntable has a weight distribution on the outer circumference to increase the actual weight during rotation, achieving a mass of inertia of 220 kg/cm2. Furthermore, the materials and shapes of the turntable rubber sheets were selected through rigorous hearing tests to ensure the best sound. A 1.3 kg lead alloy die-cast arm base is used to firmly secure the foot of the arm, preventing harmful unwanted vibrations and minimizing adverse effects on the reproduced sound. The arm is made of a torsion-resistant light alloy pipe filled with a special filler to suppress resonance of the pipe itself. The main shaft of the rotating bearing is connected to the weight shaft with weights for applying needle pressure via a rubber damper, and the bearing case and main shaft are also connected via a rubber damper. The main shaft is made of machined brass to reduce resonance, eliminating the aluminum pipes that are usually used. Specially selected angular contact bearings are used in the rotating part of the arm to equally support horizontal and vertical loads. The inside force canceller, which cancels the inside force (force to the inner circumference of the record), is a dial direct-reading type that can be adjusted in response to needle pressure. The arm lifter is equipped with an oil dump cueing system that smoothly raises and lowers the arm by hydraulic pressure of silicon oil. It is equipped with a speed control stroboscope, which allows independent 6% speed fine adjustment for both 33 and 1/3 and 45 rpm. All my products are 100% Authentic.
