After everything was as I got down to the structure. It must be said first that Kemo the board covers with a protective coating, which is very difficult durchzulöten. At least with a regulated soldering station and little temperature (300 ° C) was my hardly possible. I then washed down the paint with boards cleaners and repainted with solder resist. Caution: The paint on the front can also be washed off with platinum cleaner ... To connect my jacks I also drilled two new holes for ground lines.
After the building, then took a little longer, I've done a performance test and was first quite happy with the result. However, this did not last long, because while testing a repositioning of the connected antenna was enough to one of the transistors breathe out life. Probably was responsible for the failure here an overvoltage (ESD). Appropriate measures against overvoltage are not present in the very simple amplifier circuit. Thus, a nicely shaped paperweight from the elaborately constructed in hours of work amplifier.
My conclusion here is clear: rather buy a small ready-amplifier and not waste time in setting up this rather simple (and probably sensitive) circuit.
