RTF Smaragd BG20

Acesta este un magnetofon produs in DDR intre anii 1956-1963 si a avut cateva variante: BG20 (simplu) si BG20/1/2/3/4/5/6

Acest tip de magnetofon (Smaragd) are o istorie ciudata.

A fost produs la Uzina de aparate de masura Zwönitz, care avea traditie in electronica si mecanica fina, - facea teleimprimatoare (telexuri). Aparatul a fost produs aproape manual, in serii mici, intre anii 1955-'56 si 1963, de unde si numeroasele variante.

Anii si variantele sunt: 1955-'56 BG20, 1956-'57 BG20-1, 1958 BG20-2, 1959 BG20-3, 1959 BG20-4, 1960-'61 BG20-5 (cele mai multe) si 1962-'63 BG20-6 (foarte bun, Hi-FI) care a mers si la export. Cu aproximatie, Smaragdurile se pot recunoaste dupa lampi. BG20 1,2 si 3 au 4 tuburi: EF86, ECC82, EL84 si EM11. BG20 4 si 5 au ECC83 si ECL82, iar BG20-6 a avut 2xECC83 si EL95 si EM84.

Nu se gasea in comert, se vindea cu aprobare catre cadrele de partid. A ajuns si in Romania prin 62, -varianta 4 sau 5-, in comertul cooperatist, prin schimburi de produse ale cooperatiei. L-au cumparat (3200 lei) stabii mari si mici din cooperatie. Era impresionant ca aspect, dar Tesla Sonet Duo era net mai bun.

Din 1962-'63 CAER a permis productia de magnetofoane numai in Cehoslovacia, iar RDG-istii, disciplinati, s-au supus; nu ca polonezii...

Hi, everyone!

I'm rather late with designing my home Commons.Wikimedia page, but as they some in some countries "better later than never". I like the Commons as it is a great possibility to share images, pictures and other media stuff, and you don't have to break any law with it, because the laws are are very respected here (I know what I say, I've already fought against my permanent blocking). And this is good, because you know the present situation with this copyright violation - it's everywhere, and such foundations as Wikipedia are good at respecting and protecting such laws. I've decided to become part of this community (I hope I'll manage) and to contribute with everything I can to the Wikimedia. Thank You, everyone for taking me in, and for giving me another chance, I'll do my best not to disappoint anyone. Sil 15:11, 15 January 2007 (UTC)
