Frederic-
Your English is excellent. It is not a problem.
I have two 640's, a 645, and a 650- all are wired to the schematic. They are excellent radios after re-capping and replacing the high value resistors.
The last owner could have been trying to optimize it for one weak frequency. I am not the expert on this series but I have never seen wiring like your 640. It should take only an hour or two to restore the wiring to original. Rewiring would certainly be worth the time.
