O2+ R12k 400Mhz board schematics/BOM or component value?
I am working on the repair of my O2+, I found out that a few components "fell" from the cpu board ... strange stuff, the machine seems otherwise quite clean. See picture :

I already replaced C636 which was also missing, copied the value (1.2 uF) from neighbor C689, which I hope is right.

I need to replace that C555, how can I get its value ? Is there any schematics of that CPU board ? Or could somebody that owns the same CPU board have a quick look and tell me what is C555 ? 

Am I the only one with that strange issue ? Already capacitors went MIA in my board ...

Thanks a lot !
