What is the most ethical choice for stereo equipment that doesn't work?

[mahina]

I have to clear some space in my home.

Over the last few years I have bought several stereo systems from Salvation Army and on FB Marketplace. None of them have worked.

Should I take them to the electronic recycling at the landfill, or "donate" to Salvation Army?

Maybe someone else can make them work, but I can't. I have bought quite a few nice components and still can't play my CDs. I need the space back.

I don't want anyone else to buy them and be disappointed but also don't want to trash something someone else could find use in.

Thanks DU.
