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!
