I have a number of appliances that I purchased in the US that operate
at 60hz (120 volts) and have various digital clocks.  I use the{
in Israel and other areas where the current is 220v, 50hz.  I use
a transformer to go from the 220v to 120v and the machines {video, radio,
etc.) work fine, but the clocks are all of  because they wait 60hz to
register a second (ie, 10hz too long).  Is there any simple way to fix
or convert the clocks (can I buy a cheap chip and replace the orginal,
for example?)
Please reply directly by e-mail and any help would be appreciated.
