Description: SANSUI AU-D707F, Japanese domestic version of AU-D9. 100v. Comes w/ step down transformer. Just serviced. Circuit board behind speaker selector was damaged in shipping, tech repaired circuit board, replaced lights that were out on the tone, muting, and filter buttons. Fully tested and currently in use at my house, demonstration video has been uploaded. All functions working. Please see that. If you have any questions, please don’t hesitate to ask. This is the Japanese domestic version of the AU D9, the famed near perfect machine, put out by Sansui as part of the great AU line. This is a higher end machine, costing over $750 in 1980 when it was made. Specs from the web.
