Thanks for the quick revert Mike.
I got worried as it seems some 110V musical instruments do have problem operating in a 50Htz frequency countries.
Just out of curiosity, is it possible to convert a 110V/60Htz Metcal into 220V/50Htz machine by changing transformer or other parts. That would be a more sane solution than using voltage converter if achievable within reasonable budget.
I am sure many others in 220V counties must have faced this issue as procuring a used Metcal is easier from USA than other countries.
