It is common for the oscillator secondary to corrode through, but it is easily rewound. The tin box containing filter caps and all of the bakelite capacitors should be rebuilt, or at least those serving high voltage and/or high impedance circuits. This is a bit of a chore.
If the wet electrolytics have leaked and dried up, substitutes will have to be wired in underneath, or you can stash them inside of the original units if you prefer. There are articles explaining how to do this. Since the electrolytics are clamped at a certain point, they can be cut open at this point without it being noticeable. Be sure to observe that the electrolytics do NOT ground to the chassis.
