Up for sale is a classic, the Pioneer SX-550. The 550 sports 20 watts per channel (8 ohms), built-in AM/FM stereo tuner, one line level input (AUX), two tape loops (Tape 1, Tape 2) and a phono input for your turntable.
Just got this one back from service where it was partially re-capped and a replacement power switch was installed. Now plug and play ready for another 40 years of service.
The faux vinyl wood grain on the side panels was peeling so I completely removed it and did both side panels in real walnut veneer and finished them with two coats of Odies Oil.
