HiFi Systems AC or DC?
Hi
I need to know if HiFi Audio systems work internally with AC power or with DC because I need to know if they're frequency dependent or not (sensitive to change in 50/60 Hz in different parts of the world). The model I have in mind is the Sony MHC-GX20 sold in the U.S. (**broken link removed**) which doesn't have a 110/220 switch. Can I use it in Europe with a transformer without frequency change from 60 to 50 Hz being a problem?
Any help is appreciated
