This is a very cool vintage audio receiver, from the 1970's, four channel quadraphonic receiver QRX-7500 by Sansui. All knobs and switches are clean and quiet. The wood case is in ok condition, with some additional wear on a couple of corners, easily repairable. The receiver has performed well with the setup I had, just not used very often at all.
