I have two Altec 872a Madrid Speakers that I want to sell. My Uncle bought them back in the 70's and now I have them. The problem is I'm not sure what to ask for them. I had someone offer me $75.00 for both but I wasn't sure about that price so I told him I would get back to him. Researched on the internet, the selling price varies greatly from $3700.00 (ebay) to $50.00. The outside casing is stained and would need to be redone. I connected them to make sure they still worked and they do. Actually, they sound great. Any information/thoughts/comments/advice would be appreciated. Thank you.
