I have a vintage Bose 901 Series IV equalizer. Have had it stored in my house for a long time, and just found it during a clean-up. It's seems to be in great shape -- only imperfection I can find is one very faint scratch on the top side of the brushed metal front piece. The red light turns on when I plug it in, and the buttons and slides work smoothly. There's one listed on ebay right now for $139, but I'm not trying to break the bank. Does anyone have a fair offer for this one?
