All inputs tested and both side produces clean and even sine waves into static 8 & 4 ohm loads! No power supply hum of any kind and was measured @ <2.0mV AC. It's dead silent! All functions test fine. Following restoration procedures, the unit was ran continuously at medium volume, as all our amplifier / receivers are, into a load with "Loudness" on and both Tone Controls at 10 for 48 hours. All functions test perfectly.
 
 On our test bench, each internal amplifier of this particular unit produced peak power of 15.25 volts per channel at 8 ohms for 29 watts and 13.25 volts per channel at 4 ohms for 44 watts via discrete outputs (2x D526 and 2x B596).

Many classic Pioneer receiver fans feel that the SX-xx50 series was the better designed, better built unit internally, between the SX-xx50 and the next year's, SX-xx80 for many reasons including the use on the x50 series of quick disconnects on circuit board for ease of serviceability, extensive steel shielding to reduce noise and TO-3 style, metal cased outputs. Classic looking brushed-aluminum silver face and encased in a real wood Walnut veneer cabinet with solid Walnut corner caps. This particular one looks near new.

We have completely gone through this cleaning inside and out including all contacts, switches and controls. All indicator lamps checked and all 8 dial / meter lamps replaced with new units, for trouble-free service. We also aligned the tuner for optimum performance on both AM and FM. All functions tested for perfect operation. Power supply overhauled for cleaner performance. All inputs tested and both sides produce clean and even sine waves! Tone controls are super quality, Alps brand, "full-size", de-tented potentiometers. Following restoration procedures, the unit was ran continuously at medium volume, as all our amplifier / receivers are, into a load with "Loudness" on and both Tone Controls at 10 for 72 hours. All functions test perfectly.
