I have a vintage 1960ish record player that spins properly but has no sound. The arm of the mechanism has a, black and red, audio wire coming out if it. I want to know how to hook this specific audio cord into an independent amp? I don't want to use the phonographs built in speakers or amp. I do however want to use its arm and needle. I also should note that the phonograph has no output plugs. Please help me if you can. It would mean allot to me.
