Sansui 771 / Vintage Receiver

Klassischer Sansui Vintage Receiver. Größeres Modell der mittleren Baureihe. Ex-Neupreis lag bei 1.295,-- DM, in ca. 1974, ein Haufen Geld. Viele kleinere Gebrauchsspuren, funktioniert aber gut. Wie alle Sansui Receiver bietet er einen schönen Klang kombiniert mit top Empfangsteil, eine der Kernkompetenzen von Sansui. Altersbedingt wird er verkauft "as it is".
