Both the components are in good condition. They have some scratches, nicks and scuffs with age. The Tuner has one knob/controller missing and was replaced with a white plastic cap. Tested the amplifier through Aux 1, Aux 2 and Tuner Inputs and the speakers sounded great. I believe 2-3 controls have some oxidation issues, once the controls are set, they dont have any distortion. This amplifier is very powerful. About the amplifier, SANSUI AU-7900.
