Do I have what I think I have?

Hi, so I have several HiFis listed on facebook marketplace and someone messaged me saying I had one listed incorrectly (the PL-5) and another saying they’re priced too high. Obviously I don’t know enough about this stuff otherwise I wouldn’t be here. Would you fine folks be able to help me correctly identify and price these items correctly? It would help me and any potential buyers out a great deal. Thanks in advance!

Some folks don’t use Facebook so you might get some additional help by listing what you’ve got. You can even post pics with them here. I get it if that seems like too much trouble, but it’s just a thought.
