ECN Forum Forums General Topics of the Trade Non-US Electrical Systems & Trades Can aplliances designed for 60herts be damaged if used on a 50herts system?

I don't have a stepdown transformer so I never used 60Hz stuff here. The only US appliance I ever used (apart from a table lamp) was a radio that was clearly labelled 50/60Hz and could be set to 110, 120, 127, 220 and 240V. One old radio I know can be set to 150V. Wonder where that was used?
