Aurex SR-P90 Mega Rare Vintage TOP Turntable 80s. Japan

Description

This model was produced exclusively for the domestic market in Japan.
AC 100 V, 50 Hz / 60 Hz
The cartridge is NOT included in the package!!!
Commentary
Record player with MM / MC cartridge as standard equipment.
On the turntable,
a large turntable with a diameter of 33 cm 1.9 kg with
a finished moment of 450
kg cm

is adopted.
In addition, we adopt 3 phase switching plane drive motor of brushless & coreless 8 pole 6 coil structure for driving motor, and reliably support turntable with large diameter hard stainless steel shaft of 10 mm φ.
Quartz PLL system which controls the phase difference by comparing the reference signal of the quartz (crystal) resonator with the speed detection signal is adopted.
For rotation speed detection, FG coil that generates power by changing magnetic flux density of magnet and motor rotor is adopted.
In addition, the speed control system adopts a newly developed IC with digital memory inside the IC.
In this method, unlike the conventional sample & hold method, since the coil resistance is not used at all, temperature characteristics and stability are improved.
The tone arm adopts a rigid champagne gold anodized finish straight pipe arm.
It is a high sensitivity type compatible with Roman, and it is compatible with lightweight cartridges.
In order to realize high sensitivity, pivot bearings are used for the vertical direction and underground contact bearings are used for the horizontal direction for the bearing system.
In addition, aluminum alloy die casting is adopted as the head shell, and connection with the arm is taken as a miniature lock nut.
All connection cords and connection connectors are subjected to gold plating, and furthermore, we are pursuing high sound quality, such as making the cartridge line a litz wire and the arm code a special parallel cord.
The static type anti-skating mechanism is carried.
The solid state auto lift up mechanism is carried.
This mechanism projects light from the LED towards the mirror attached to the tone arm shaft and receives the returning light with a photoliver to detect the angular velocity (movement of the arm).
Because of this, it does not have any mechanical contact points, it is not affected by the internal transformer etc. because it does not use magnets, etc., and accurate and quiet auto-up operation is realized.
When turning to the start / stop switch, the turntable first rotates and the tip of the needle descends to the record side.
And, when the performance finishes, the arm automatically stops from the record side and stops in the up state.
During record playing, when you stop halfway, when you touch the start / stop switch, the arm automatically ups up, the turntable keeps turning for about 4 seconds as it is, preventing the pitch change sound when stopping.
Also, even when you want to start from the middle of a record, take the arm to the desired position, touch the start / stop switch, the needle tip gets down to the code surface and starts playing.
MM type cartridge (C - 70M) and MC cartridge (C - 80MC) are equipped as standard on the cartridge.
The MM cartridge C-70M uses a 0.6 mil round Ultra C needle and has wide area reproduction characteristics of 20 Hz to 22 kHz.
In addition, the MC cartridge C-80MC can enjoy a wide band of 20 Hz to 25 kHz and the sound quality unique to MC.
In addition, the C - 80MC has become a high output type, and ease of use is improved, such as needle exchange can be done with one touch.
In the cabinet, we adopt two layers of high rigidity cabinet which are crimped high density particle board and 6 mm thick iron plate as two materials with different resonance frequencies.
In addition, by making the center of gravity of the cabinet and the center spindle of the motor coincide, it suppresses mechanical torque change (ripple) called cocking, achieves low wah / flutter, and obtains stable tracing capability.
For the insulator, we adopt a structure which is difficult to move in the horizontal direction.
