Classe Seventy amp found in alley

Sitting in my downtown alley was this Classe Seventy amp. Other than a little bit dirty and having some sort of felt glued all over the top, its condition is good. And after hooking my Dynaco preamp up to it with some average speakers, it works fine. I'm still trying to figure out if I stumbled onto an abandoned, stolen item or maybe it was found in a move-out pile and the scrounger couldn't sell or trade it so he dumped it where I found it. It's kind of heavy. So did I find something desirable?
