Dual CS 520: Data Information And Technical Characteristics.

I would like to introduce my "new" turntable, a Dual CS 520 Full-Automatic Belt Drive. I bought this turntable to replace the PD-D 351 Electronica Industriala, my old Romanian turntable, which is broken and waiting for a major repair operation, restoring the electronics board and maybe a new motor.
In the picture below you can see the Dual:

I have found it on Internet and it is coming from a very reliable source of analog audio equipment.
Few technical characteristics:

• Manufacturer: Dual;
• Model: CS 520;
• Was produced between 1983 and 1986;
• Manufactured in Germany;

Now it is fitted with an Audio-Technica AT91 cartridge.
