Raduga (TV)
Raduga ( Russian for "rainbow") is the brand name of the devices of the Saint Petersburg Kosizki television equipment factory ( Завод им. Козицкого ), as well as the name of early experimental color television sets without series production.
The Raduga brand devices were among the first color television sets available in the GDR . While in the 1970s you had to pay around 3,500 marks for a GDR color television set Color 20 with an already fully transistorized chassis , the tube-equipped Soviet Raduga was a bit cheaper at around 3,000 GDR marks. The devices are now considered cult objects and are still remembered by many mainly because of the technical defects:
- The devices were only equipped with a SECAM decoder by default, so Western TV could only be received in black and white. A PAL decoder could, however, be retrofitted.
- The picture tubes (59LK3Z) sometimes had severe convergence errors , which resulted in the picture being broken up like a rainbow at the edges.
- The synchronization was not stable in the first few minutes after switching on.
- The circuit was built with many tubes that had to be replaced from time to time. However, they were of a non-standard size and were difficult to obtain.
- Due to the design, some Raduga televisions burned down (hence the term "home bomb" was used for them), which is why these devices were sorted out and scrapped in public institutions in the 1980s. TV fitters were also instructed not to repair defective devices in private households.
Raduga televisions are still made today, but they don't have much in common with the old Radugas.
