Welcome,
Keep in mind that alot of the old vintage electronics, if in working order can bring you much , much more than scrap value. If you have any items with tubes in them $$$$. Any older 70s stereo equipment like
Pioneer, Marantz, Luxman ... to name a few can bring you big dollars on E-bay or Craigslist. Even if it does not function some of the really high end stuff I sell for repair and believe me it does sell ! And for way more than scrap value.
Vintage speakers - the same scenario - even if the surrounds are shot. I urge you to look up the models of what you have to see if they are selling and if some , clean em up , test them and make some $$$$.
Good luck,
