Be careful, I have seen switchers that looks almost like analog per
your descriptions and few analog ones looks like complex switcher.
Switchers: Only talltale item: solid ferrite core and small, tends
to have copper band; switcher. Analog PSU tend to have soft iron
lamites and bit heavy and tend to hum like a bee sometimes.
Switchers sometimes squeal and usually quiet.
