| The use of 220/230v mains vs 110volts (which most of the
world thinks
| quaint) more than compensates for 60 vs 50hz. (Yes, we
know that 220v is
| available in most US homes , with a bit of help from an
electrician.).
| We have been using transformers made for 60hz down here
for yonks and
| problems are rare.
