schemawijziging (?) BX645U (Techniek Radio/TV)

Dear Forum members

Recently I restored the above set. I found one major difference in the schematic and the actual set.
1. In the schematic the filter condenser consists of C1 + C2 50ufd each whereas in the actual set there are two capacitors C1 + C2a in one CAN 50ufd each and the third capacitor C2 also of 50ufd in a separate can. So in all there are three 50ufd capacitors.

2. In the schematic the main resistance is R1 of value 1K ohms but in the actual set it is R1 + R1a each of 820 ohms.

There is no mention about this in the documentation. Can anybody let me know as to when this change was done?
