The front looks decent. But no more than that.

The top is a war zone which looks terrible.

It is also a horror at the rear. You should not restore a chassis like this. Because some think this is original.

The repair trestle proves to be a useful tool. Thanks Ben.

Everyone will understand now that I don't care what you think. Whether or not the chassis may be restored. It is my property and no one else has anything to do with it. And yes I'm done. with the dear understanding full collectors.

The plate detector is a strange design in this device.

Testing the fourth HF circuit.
Philips 636A foto 47
It is sometimes very difficult to get the synchronization right because the tuning capacitors deviate too much.
