PIONEER STEREO RECEIVER SX-1280

My father had passed me down his old "PIONEER STEREO RECEIVER SX-1280" now i have finally upgraded and am looking to sale it....This receiver is in great condition for its age,it has maybe 1 scuff on the wooden exterior about 1 inch long yet it is not even very noticeable.The 50Hz knob is missing,and as far asi know it has never been serviced.But most importantly this vintage receiver works like a a champ and i am very fond of it but i have upgraded and at this moment need the money.
