Wall plug included. There's oxidation on volume knob, which causes crackling when changing volume, it takes a little finesse to get both channels to be at correct volume because brushes are not making good contact(this thing is 30 years old). This can be fixed by dubbing it in alcohol(or this http://www.kontaktchemie.com/KOC/KOCproductdetail.csp?product=KONTAKT+60), but it will come back after a while, because protective layer is gone. Other than that everything works perfect. Has been stored in a dry dust-free place.
