explanation
A record player that uses a quartz lock servo system.
The quartz lock servo method compares the output of the FG (frequency generator) with the
phase of the reference oscillator and applies the servo, and by adopting a highly stable
crystal oscillator as the reference oscillator, the speed deviation is reduced to 0.003%
We have succeeded in suppressing it within.
At the same time as pressing the stop button, the power to the drive circuit is turned off and
the brake that stops the rotation of the turntable is activated.
It is a mechanical system that combines an electromagnetic plunger and a lever, and stops
at about 1/3 turn when it is 33 1/3 turns.
It has a sandwich structure with a steel board and an insulator sandwiched between
a wooden case.
The steel board increases the weight, and the special sandwich construction keeps the
lowest resonant frequency of the cabinet low enough to resist feedback.
In addition, since the steel board is a shielding material, it also works to prevent the leakage
flux from transformers and motors.
Regardless of the power frequency, a frequency illuminator is adopted that is proportional to
the number of revolutions.
The neon lamp built into the strobe illuminator is controlled by a crystal oscillator.
As a result, it always operates at an accurate frequency, eliminating anxiety factors such
as flickering of strobes using conventional power frequencies, and suppresses errors in setting
the rotation speed.
It is equipped with a statically balanced arm with an effective length of 237 mm.
It is a highly sensitive type with an anti-skating mechanism and lateral balancer, and the height
of the tonearm can be adjusted.
