SANSUI Amplifier AU-α607MR Due to its age, there are some stains, dirt, and rust. I haven't turned it on in the last few years. When I tried to listen to it again recently, the volume control seems to be broken, and I can only adjust it to zero or maximum. I haven't checked it thoroughly, so someone with more knowledge might be able to figure out the cause. Please understand that this is being sold as junk.
