Christoph,

You probably need to use about 130uF or more for the capacitor.
The symptoms you give are that of a too-small capacitor.
As you increase the cap value, it will work better and better
until you get the resonant rise etc.   Your variac should be
fine.  I also updated and improved my description for
selecting the correct cap value at my website:
