I was in Amsterdam over the new year and visited the Energetica museum there. It's in an old power station and most of its exhibits relate to electricity rather than electronics. They have a nice little collection of Philips radios and TVs, some of which are demonstrated. No standards conversion problems there!
All the labels etc are in Dutch but the guys who run the place speak English and demonstrate with enthusiasm. Recommended. Especially if your interests extend beyond wireless/TV to power generation, distribution and domestic appliances.
The web site:
http://www.energetica.nl
is in Dutch only but Babelfish makes a stab at translating it.
[slightly OT] The museum is only a short walk from the Ij Brewery for those of you who are interested in this important field of engineering
