I know very little about this Sony amplifier. My neighbor gave it to me when he was moving. Said it works fine but I don't really know how to run it. When I plug it in everything lights up and all the functions seem to work but I don't have speakers so you have no way of knowing for sure. It may have CDs in it as I tried to put one in and it wouldn't take it. I don't know how to eject the ones that are in it if they are. I'm selling as is and starting at low price for that reason.
