Classic Sansui Amp from the 70s. I have enjoyed the unit for over 20 years but simply do not use enough anymore. Time for someone else to enjoy. Everything works as it should. There is some static when changing the volume. Sounds just fine after one stops manipulating knob. The volume pot is sealed & in order to remedy one would need to replace the volume pot. Some people drill a hole so they can blow it out...I am not going to do that. Scratches to note on top, sides & rack handles. Shoot me a message if you have any questions.
