Almost all ungrounded consumer equipment has a small amount of leakage
that you can feel, especially if you run the back of your finger over
metal surfaces. In the case of the Sony ICF-2010, the primary to
secondary capacitance in the AC adaptor is the culprit. This leakage is
quite small and totally harmless.

The wiring in your house may or may not be faulty (I suspect not) since
that has nothing to do with what you are observing. Besides, the
ICF-2010 adaptor plug is non-polarized so it can be inserted either way
into the outlet. You will note that the leakage is there regardless of
which way you plug it in.

BTW, since most electronic equipment has this leakage and people find
it annoying, most office, industrial, and educational equipment is
third-wire gounded. This also prevents "additive leakage".
