When you look at this thing, its hard to believe its over 40 years old.. Looks like it just came out of the box. Turns on, lights fire up, the only problem is when you press play, it thunks like it is going to play, then thunks again back into idle. When you press forward or reverse the heads move in their direction, but will make same thunk sound and cease moving after a few seconds. My best bet is that it needs some module replaced, which seems easy but not my cup of tea. Saw a guy online with the same problem and seemed to be an easy fix. Message me for more details, want someone to have fun this cool piece of history!
