hello to all members , thanks again for the help to determinate the correct model , on the first look detect changes on the power supply (cams from same old technician) , this guy cut the AC selector ( 240v ,220v ,150v ,125v ,110v ) of the radio and the original AEG B 300 C 75 diode... .

As replacement diode use the B280C 800Si ( old technician replacement not my choice. ) 

Before plug the radio again to my country power source ( 230v ), remove all tubs of the radio and measure the high voltage on the pins 7 and 9 of EL84 tube, pin 9 give me 350v dc pin 7 give me 340v dc .The original schematic have on pin 7 250v dc and on pin 9 230v dc . Hear i need help, how to tune the voltage of the power supply with the correct voltage , please give me advice ,is very important to me on my country is very hard to find a specialist to repair the radio .

Photos of transformer and the diode :

Thanks very mach
