About the audio equipment: it's a Sony compact stereo from the late 70ies with only radio and tape deck, intended to work nearly everywhere. You can set it to 100, 120, 127, 220 and 240V, works on 50 or 60Hz, but has a standard unpolarized, ungrounded American plug.
I found some nice pics, try to post them (some taken in the US, the family I was staying with once had rather strange arrangements in their NYC appartment, some from a german DIY book "Basic electrical repairs easy done", contains pics and wiring schemes, some taken when rewiring an appartment.)
Question: What are those standard US switches called? I mean the light switches with a small handle sticking out of them.
I like them, they were common around here in the 50ies and early 60ies, was rather surprised to find them everywhere in the US.
A little bit late, but merry x-mas to all.
