Transformers are rather expensive to use for supplying transistor radio's, because of the idle draw. The Watssound consumes 2.5W when in use, but 1.0W when switched off. This means that plugging, but not using this radio costs you about 2 euro's per year. I made an experiment to replace the transformer by a small switched mode power supply, which reduced the consumption to 0.1 (off) 0.7W (in FM).
