ONKYO SC-380: Data Information And Technical Characteristics.

I will prepare in the next few weeks a new set of movies with the new equipment I have recently added to my collection.

Before doing that, I have one more presentation to make: my set of speakers – ONKYO SC-380.

I have these speakers from the same reliable source from where I have bought the turntable.

Technical characteristics: 

• Maximum power input: 100W;
• Impedance: 6Ω;
• 3 way system;
• Frequency response: 45Hz – 33 KHz;
• Sensitivity: 90dβ.

Before making new movies, I have one more problem to fix: my camera. The sound recording of my camera is horrible; I will try to use a different one.

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;
• Color: satin-metalic;
• One output RCA connection;
• Belt drive;
• Full-automatic;
• Speed: 33 1/3 and 45 RPM;
• Signal to noise ratio: 72dβ;
• Wow and flutter: ±0.07% / 0.045% DIN / WRMS;
• Original cartridge: DMS239.

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

Rostov 105: Date, Informatii si Caracteristici Tehnice.

Pe  parcursul procesului de documentare, desfasurat in avans sau in paralel cu activitatea de restaurare, am reusit sa gasesc diverse informatii legate de dispozitivele la care lucrez. Aceste informatii au fost gasite pe forumurile de discutii Romanesti si Rusesti, m-am folosit de Google Translate si am facut cautari zilnice filtrand postarile noi.
M-am gandit sa postez aceste informatii, in ideea in care un utilizator interesat le-ar putea gasi pe toate intr-un singur loc (va rog sa priviti cu ingaduinta eventualele discrepante care pot sa apara, in principal din procesul de traducere).
Azi as vrea sa descriu continutul pachetului de livrare la achizitia unui magnetofon nou (interesant de vazut cum era privita livrarea in acele vremuri, comparativ cu exemple recente cand la o imprimanta nici cablul de conectare USB nu il primesti - cumperi un produs, il scoti din cutie si nu il poti folosi, trebuie sa revii la magazin si sa cumperi un cablu):

• Magnetofon Rostov 105 Stereo;
• Rola 18cm cu banda;
• Rola goala 18cm;
• Cablu de alimentare;
• Cablu pentru inregistrare din sursa Radio, Televizor, Amplificator;
• Cablu pentru inregistrare din sursa Pick-up, Magnetofon;
• Cablu pentru inregistrare din reteaua de radioficare (de la "difuzoarele" din casele batranesti, la un capat are conector DIN iar la celalalt are stecher cu doi poli);
• Curea de rezerva pentru contorul de banda;
• Sigurante fuzibile de rezerva (trei tipuri de sigurante corespunzator celor folosite in magnetofon: 5A, 3,15A, 1A);
• Bec de rezerva pentru iluminarea VU-metrelor;
• Instructiuni de folosire si o mapa cu schemele electronice, cablajele aferente si schema cinematica;
• Cutia in care magnetofonul era ambalat.
