Thanks!

Unless you know that what you have is some piece with historical value or is very high-end but just broken, I'd say just recycle them.

Taking them to SA or Goodwill could easily result in it going to someone that will just throw them away upon failure.
You can't be sure everyone is as responsible as you regarding proper disposal.

And those parts will never be seen again. I dare say some hobbyists would part them out on eBay. Remember, replacement parts from China are more expensive or non-existent now.

I would google to see how much they might be worth as is or restored. I had a turntable restored last year and the repairman said he had customers willing to turn me a nice profit if I put it up for sale. Otherwise I’d donate the items back.

As far as the CD’s, I downloaded all the music to an SD card and can pretty much play everything off of my phone (Sorted by artist, genre, etc). I even digitized all my old vinyl too. Good luck!

You can leave it on your doorstep for pick-up, or meet somewhere close by, or arrange it however is most convenient for you. And feel good knowing that wherever it winds up, it's because someone actually wanted it, not because it was discarded.

Good luck!
