Here is a vintage Pioneer SX-780 receiver produced by Pioneer from 1978 to 1980. I am the original owner and kept it in operation until recently due to moving to a fully wireless system.  Everything works.  It is in very good condition aside from some scratches and chips (see pictures). Price includes original operating instructions and factory circuit schematic diagram (see picture).


If you have any questions about the condition, operation, or anything you see in the photographs or video, please ask before purchasing. I am happy to provide additional information or additional photographs when reasonably possible.
