蘇聯冷戰時期產品

Klingon-Hifi made in USSR during the cold war

Please keep in mind that Soviet economy was not "supply and demand" type, but rather (and sadly) planned from the top economy.
So when factory X was given an order to build let's say 1,000 amplifiers a year nobody there cared about marketing or sales. They simply built required quantity and shipped
them to the retail outfits.
As a result design was not a first (or second, or third) priority.
For some designers Pioneer, B&O or Sony or whatever catalogs provided all the inspiration needed.
