Summary
[edit]DescriptionSoviet 'Sezam' intercom speaker, early 1990s (2).jpg |
Русский: Сoветский/российский квартирный блок домофона "Сезам". Примитивный симплексный телефонный приемопередатчик, он же "активная колонка" (на редкость крикливая! мертвого разбудит). Два германиевых транзистора + выходной трансформатор. Годы производства компонентов 1990..1992. English: Soviet/Russian 'Sezam' door phone (intercom). This is a primitive simplex telephone, with two germanium transistors transformer-coupled to the speaker (which serves as a microphone in send mode). The "active speaker" is surprisingly loud for its size. Parts made in 1990...1992. |
