I bumped into a guy who scored on two clean Altech woofers that appear to be 15" but he thought were 12", and two Altec horns. He bought them and other gear for $250. Once he figures out what he's got, he plans to sell them on eBay. I suggested he check out US Audiomart, but he prefers the Bay.
I thought those interested in such equipment might like the heads up. I don't know when he will list them nor do I know his name. He lives in Albany, Oregon.
Not much to go on, I know.
