Pioneer SX-850 Stereo Receiver

Audio Proz Inv #: 72884

Beautiful, silverface vintage Pioneer design. Capacitors in power supply were replaced and upgraded. Old caps weren't bad but were upgraded regardless. FM indicator bulb was replaced, has a slightly stronger orange glow than the rest of the indicator bulbs but it looks nice. All controls and connections were double cleaned and tested. Relay was removed, cleaned, serviced and re-installed. Solder points on power supply board were reinforced and made more rugged. All 2SC1313 transistors were replaced with 2N5500 lower noise type transistors. Some resistors in power supply were upgraded as the original parts are known to heat up over time. 6db pad added to amp board for a nicer range/ response from the volume knob. FM was calibrated and has excellent stereo lock-in as well as signal strength. Faceplate and display are in good condition, some light scratches on the top of faceplate. Wooden case is in great shape with only some minor signs of wear on the corners/ edges. All controls and connectors are in good condition with only light signs of use and wear. Very low use unit, cosmetically and functionally great. #8+ condition.
