/diy/ - Do It Yourself

Today I found a radio system nearly 30 years old while I was cleaning my mom's house. It belonged to my beloved late father.. I spent my childhood clicking it's button and saying "Break break are you there break!". Now I really wish to make it work again. It's like a connection between the past and present for me.. Anyways, I took pictures of the parts..
I hope you can give me some clues about turning it on..

I really need your help to connect these parts to each other.
(I uploaded the pictures on a different site to keep them in high quality)
