Hello,

I am trying to fix my Beogram CD X. I am now checking supply board and find weird fact in the schematics. The capacitor with number 2473 (the one in the air soldered to decoding board) should be 1nF 30V regarding the listing on page 2-2. In the schematic on page 1-4 is written 47n as value. The reality (in case of my board) matches the schematic on page 1-4 as there is 473 M5C capacitor... 

What is the proper value?

Another inconsistency is in case of 2640. There is the same value in schematic on page 1-4 and listing 2-2 where the value is 1500uF 16V, so I believe it should be as stated. But there is 1000uF 16V on my board. Is it normal or somebody mess with it and changed the capacitor for another value?

Thanks

The cap is 47 nF, but all this doesn’t really matter.

It’s a Philips CD 104 at heart. 

It left the factory with these components. Replace with same values.

Do I understand correctly that the 1000uF instead of 1500uF was installed standardly?

But I understand what you saying, just curious and want to be sure.
