I have it soldered together now. It seems to work…
What I don’t quite understand is, why I am only getting 5.2 Volts on the output side? This transformer should output 8V when wired in parallel.
Is it possible that I wired the voltage switch the wrong way? When I set the switch to 230V, I get about 10V. (My AC mains is 120V).
Here is the datasheet of the transformer:
Maybe I am just not understanding something? Sorry, I am new to electronics!
