Hi guys,
Several days ago, I wanted to open the under cover of my beloved Leben CS-300X limited edition. What I found was weird. I loose wire from the filtering section of the rectified AC to DC from the transformer, the power supply (I think, I'm not an expert). I will show you below two video samples of that so it's gonna be very clarified.
As you can see, one of the ELNA capacitors (the third one of the four counting from the left) has one lead unused. No electrical contact. And I think that's not good! The strange thing is that the amp has been working perfectly and sounds terrific with my Sennheiser HD800's.

There are some pics I have found on Google in which I can more or less see that green wire soldered to the left lead of the cap. Examples:
Anyway, I don't know for sure that I have to solder that wire to the lead. The pictures are not 100% of evidence. I expect that the different voltage ratings ( EU / USA) (230/240/120) have nothing to do with this regarding the design. I need your help by posting a good pic of this part before risk of blowing up my amp.
Thanks.
