Magnavox

I recently purchased a Magnavox record player/AM/FM radio/tape player (some kind I've never seen). Its a console with the radio behind a front sliding panel and the record player on the top under a sliding door and the other side has all the electronic parts. We want to try to fix it, but want to know what the model is and whatnot, but I'm not sure how to find it.

As to fixing it, the console turns on, but the radio doesn't tune. We haven't been able to really test the record part and have no idea how to try the tape player. I've been searching online, but haven't seen one like it yet.

Any suggestions?
