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.

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.

- 22000er Elkos
 
−
- 2 Netzteile, das schwarze nur für die Endstufe, das Kleine für Lampen, Klangregelung, Tuner, Phono, Vorverstärker.

−
- 220V 240 V Umschalter, bei 225 V Steckdosenspannung wird die Endstufe mit 54 VDC versorgt ( Stellung 220 V )
 
−
- Stellung 240 V : 50 VDC, das ist zu wenig, laut Service Manual sollen 54 VDC an den Elkos anliegen.
