Weird Night!

Wow the weirdest, thing just happened, My 1973 marantz 2270 receiver's, dead tuner section just, started working out of the blue!, i was going to play a cd & thought i turned it to Aux, when i turned the volume up i heard AM Static, the tuner section never worked when i got, back in 03, its just plain weird!.....

I got the receiver from a friend's brother, he had gotten it from a friend, who said there was a short in a wire, i never found the supposed short, the last time i had it open was around christmas time, to clean the pots, with tuner control lubricator (contact cleaner), it just plain weird, i wondering if it has something to do with the storm this afternoon.
