K1803, assembly pictures wrong?

Hello!
I bought K1803 “UNIVERSAL MONO PRE-AMPLIFIER” amplifier to my microphone and assemblied as shown on the manual (this one velleman.be/downloads/0/illu … 3_rev1.pdf) that came with it.

Well it doesn’t work… after that I started checking what’s wrong and found out that one capacitor (C2) is positioned wrong way in those assembly pictures.

You can clearly see (http://www.velleman.be/images/products/0/small/k1803.jpg) the right direction from photos but on pages 6 and 7 on the assembly manual that direction is wrong, am I right?

Hopefully you can fix this, I’ve done many hours of needless work because there is a small flaw.

The manual and PCB are correct. Only on the picture the capacitor has the wrong polarity.
