My dad found an old phillips MW, LW pushbutton radio, and amp in the attic today

After a bit of fiddling something resembling static could be heard but no radio stations. So I did the instinctive thing and pulled it apart, well at least removed the covers, the bulb for the dial was broken but didn't notice anything else. Put it back together and no static could be heard
Would it be worth trying to get someone to repair it, how much could it cost to be repaired? Is there a chance of trying to do it ourselves (I have played with electronics before, but nothing like this)? If we do where can parts be found? What are the most common things that go wrong with them?
Many thanks,
Chris
