Hallo Mario, Dave,

That's what I thought as well 15 years ago. Then I blow up the diodebridge
and the fuse. I noticed that this 9V AC is rectified as well, inside the
C64. This means there is no galvanic isolation and thus no free use of the
9V AC.
FYI: I wanted to generate a simple +9V and -9V by connecting one pin to GND
and using two diodes connected to the other pin for generating these
voltages. This simply meant that at one phase the diode shortcircuited the
Transformator.
