To accomodate the hefty 12V single rail, SMPS transformers used are on the fat side. Fortunately, big is beautiful when it comes to conducting current. Chokes used on the output filters are huge too, with thick motor wire to ensure minimal resistive loss.

Attention is paid to mains noise, with common mode chokes spotted right at the input. With 1k2W to pump, it had better not trip the house every now and then. A pair Panasonic capacitors handle high voltage filtering. Sad to say, neither the Olympia or Everest adopted high temperature 105 Celsius rated parts. Again, Taiwanese capacitors lined the output.
