Please help me!
I just purchased a Duo-R which has an RGB-modification. It has a scart lead directly attached. The picture is sharp, but unfortunately very dark, which means the signal is too weak. I opened the Scart connector and had a look inside. There are 3 transistors and a resistor, so this *should* be an RGB signal booster.
There is a black cable which touches the metal frame (it's not soldered to it), could that be the cause?
Please have a look at the fotos I took.

That is not an amplifier. That is just capacitors and resistors that you need on the lines anyways.
You can find a true RGB amp over at www.gamesx.com (http://www.gamesx.com/). It's also easy enough to use a CXA1145 or CXA1645 to do the job. If someone wants RGB when I do S-Video, it's quite easy since I use a 1145 or 1645 for the S-Video already.
So in short, you won't get a good signal from that cable no matter what you do.

Thank you for clearing that up. Just now the CD drive has started acting up. The laser must be really weak; when it arrived this morning I tried out CD-Rs and it couldn't read them (they work fine in my other Duo and Duo-R). At first it did at least play original (non back-up) games. Now it takes a long time to load and the music doesn't play anymore.
I guess I'll simply return it to the guy who sold it to me- after all there are no replacement CD-Rom mounts/lasers available anywhere in the world :-(
