Toshiba SA-320L??? Any Info?

I walked past this the other day and decided to buy it. I got it for $10. It looks really nice but unfortunately one channel has gone. I haven't given it a full clean yet though and there are no blown fuses. Does anybody have any info on this Receiver? I've seen it on two e-bay listings one says its 70wpc and one says 50wpc. I doubt that it would be over 40wpc looking at it, the model is SA-320L. Does anyone know about this model?



Thanks!

In germany your receiver called only SA-320, from a TOSHIBA broschure 1978.

HiFi-Stereo-Receiver SA 320.
Der SA 320 hat die optimale Leistungs-Dimension für HiFi-Interessenten, die einen normal großen Wohnraum nicht mit einem überdimensionierten Steuergerät ausstatten wollen.
Die Sinusleistung im 2-Kanal-Betrieb beträgt 2 x 24 Watt bei 1.000 Hz und 2 x 18 Watt bei 20-20.000 Hz. Musikleistung: 2 x 27,5 Watt.
Der SA320 ist mit OCLTechnik ausgestattet. Das ist eine kondensatorlose Direktkopplung der Endstufen,die mehrere Vorteile bringt.
1. Der Frequenzgang wird nach oben und unten beachtlich erwei¬tert.
2. Der Klirrfaktor wird wesentlich niedriger gehalten als bei herkömmlicherTechnik.
3. Der Dämpfungsfaktor liegt günstiger
Der SA 320 hat wie der SA 420 einen PLL-Decoder und durch die Verwendung der gleichen Elemente, wie 3-fach-Drehkondensator etc., auch die gleiche Empfangsqualität.Hoher Bedienungskomfort ist auch beim SA 320 selbstverständlich.
Anschlußmöglichkeiten:
Ein- und Ausgänge für 1 Tonband¬gerät,das auch über eineDIN-Buchse angeschlossen werden kann, für Plattenspieler, für ein weiteres Gerät über 1 Auxiliar, für 2 Stereo-Lautsprechergruppen, für Stereo-Kopfhörer

I remember noticing that that series of Toshibas have unusually low damping factors, so that might have an effect on what speakers sound good with it.

Hopefully cleaning all of the switches thoroughly will do the job. I have a SA-725 and, while not in rotation, it's as beefy as the Realistic receivers I have. Good luck!

I did a thorough cleaning of all pots and switches but the one channel is still gone

If its not the preamp I have an idea for what to do with it... and turn it into an 80Wpc receiver!
