Hello Everyone. I'm not sure anyone will know about this but i'll try anyway. Unfortunatly, The only amp I have in my house that can drive my home-made speakers is an old Grundig Tuner/Record/Tape player I got off someone down in my basement. Okay that's fine it works good. But. It's old and Doesn't have any RCA inputs, etc. All it has is a mic input and another identical cassette input on the back. They each have 5 different pin holes for the proper connector. I was thinking that I might be able to just stick wires in the appropriate hole and wire it up to a cd player, but I'm not sure which different hole is for. All help appreciated! Thatnks in advance.
