Nice start Nino, I'm sure it'll come up every bit as good as your other restorations. I'm looking forward to the updates. 
I have a question though. The disconnected braid wire sitting in the bottom left hand corner of you cabinet, what does it connect to? The reason I ask is that my Flash Gordon has a loose braid wire in exactly the same place. The bottoms not falling out of mine but other than that, your picture could have been a photo of mine.
The ground braid on the rear right hand side is meant to connect to the ground braid in the head. You will find a screw on a horizontal section of the head. If the ground braid is not connected, you can experience strange issues, so make sure it is connected !
