Stereo questions...

So, I was able to get the little original radio working ok. But it's not long for this world I am sure. It's just nasty as all hell on the inside. I blew it out with compressed air but it's still bad. SO I have a really nice Kenwood AM FM auto reverse cassette. Yeah. It's old, but in almost new condition. I think I want to use it. Here's my question. I know everybody's goin to stuff like bluetoof, flash drives and all that hoorah, but that's not for me. Does someone make something where I can attach a remote CD changer on what I have?
