Offered here is a beautiful Pioneer model SX-850 AM/FM stereo receiver in fully restored and serviced condition.
This receiver is from my collection, was restored and serviced by me a few years ago.
I repair electronic test equipment professionally, my hobby is vintage audio.
All electrolytic caps replaced, including the large main units. Film caps installed where practical. Chassis throughly cleaned, Alps slide switches were carefully removed, disassembled, and refurbished, not just "sprayed". 
Improved heat sinks on the power supply board.
Completely adjusted, tuner aligned and tested.
This receiver was in my listening rotation, and is one of my favorites. A very sweet sounding receiver!
