I am new to this forum, and I have a question for you experts. I have an old Bell & Howell speaker that goes with a small tube amplifier. The speaker outs are something I have never seen before. They are half inch round plugs with two holes. Both ends of the cable would need to be male ends. The person I bought this from is a stereophile, and he had never seen anything like it. His temporary solution was to rig the cable with two bent over nails. This isn't exactly ideal for sound quality or safety. Any help on these connectors or an original cable would be great. Thanks for the help.
