Anfang 1978 stellte Toshiba eine ganze Baureihe neuer Receiver vor, der zweitgrösste war der SA-7100.

__NOTOC__
−
Das Designkonzept sieht den damaligen populären Pioneer Receivern nicht unähnlich.

Einzigartig ist aber die schöne Frontklappe welche gedämpft runterfährt.

Dieses Gerät hier hab ich auf Ebay-Kleinanzeigen für wenig Geld ergattert, Infos gibt es im Netz wenig, ausser auf Good Old Hifi.

'''General'''

Der SA-7100 ist ein analoger Receiver mit kräftiger Endstufe. Faszinierend sind die Anfassqualität der Knöpfe und Schalter. Alles aus Metall, Schalter rasten mit Schwung ein. Dieses Gerät hier ist 36 Jahre alt uns es funktioniert völlig einwandfrei.
