Revitalized Vintage Sansui QR 6500 Receiver - This Sansui QR-6500 was one of Sansui's first contributions to the quadraphonic genre. It was produced from 1973 to around 1975 and produced 33 watts per channel into 8 ohms when all four channels are driven and 37 watts per channel when each channel is driven. It retails at $750.00 and has a very distinctive design. The gold-silver front panel pairs nicely with the darkened dial window and green-amber lighting. Put it all in a nice walnut finished solid wood enclosure and you have one very nice looking receiver.
