Anyone runs Euro voltage power amp or integrated with transformer ?


There is some interesting 220v/50hz stuff. Transformer doesn't change frequency, though.

I've had no hum or any other anomalies. Still always kinda bothered me in the back of my mind for some reason. Tried to get them switched but nobody wanted to mess with it in my area. 
This wouldn't bother me but I would not use cheap Chinese transformers, that's for sure.

Example is Gryphon. They said they wouldn't convert to North American voltage, and there are many more Gryphon pieces for sale in Europe than here.
