These appear to be pretty old 60's(?)......They have a sealed cabinet with one screw in read top and bottom. No badging. One does have what appears to be a serial # stamped on the rear near the connections screw terminals. They sounded amazing - .......until one of them blew. I'm excited to open the cab and see what I've got. Just not sure how to approach disassembling. Thanks for any tips!
