Pioneer SX-1050 Vintage Stereo Receiver for sale in East Brunswick, NJ
Pioneer SX-1050 Vintage Stereo Receiver. Beautiful cosmetic shape. I just had it completely taken apart and cleaned to include cleaning and freeing up the frozen pots (see last pick). All the capacitors were checked to include the big power caps which were deemed in good shape and not in need of replacement. The variable resistors on the power board were checked as well as all the contacts cleaned. Was given a clean bill of health. I have tested the phono and aux settings and connected it to a variety of speakers and both channels work. Like any vintage receiver nearly 50 years old anything can go wrong down the road but this is a highly sought after receiver in line with the highest power Sansui and Marantz systems. Seems to get great reviews. if you feel you want to pull it all apart and replace all the components it's your call. Pickup cash only. DescriptionHigh sensitivity, outstanding circuit design in a new AM/FM receiver.The Pioneer SX-1050 puts every significant AM/FM receiver feature together in a strikingly handsome package.From a highly sensitive FM front end, a high selectivity IF section, to the low distortion, big power amplifier section that delivers the outstanding continuous power output of 120 watts per channel min RMS at 8 ohms from 20 to 20,000Hz, with no more than 0.1 % total harmonic distortion, the SX-1050 radiates the excellence that the stereo buff has come to expect from Pioneer electronics.Such features as a phase locked loop IC in the MPX section, the audible multipath switch that helps eliminate FM wave interference, and the highly advanced equalizer section are not just extra touches in this receiver, but exemplify the considerable thought that has been applied to the overall design and circuit of the SX-1050.Other important contributions to flawless sound include the Pioneer Twin Tone Control, the Toroidal-core transformer, the two very large capacitors in the power supply section - all calculated to reproduce the sound spectrum with stability arid full component protection in the inimitable Pioneer style.SpecificationsTuning range: FM, MWPower output: 120 watts per channel into 8?
