Hi!

Anyone else having a humming problem with kenwood hc-10 clock? I have just bought one used. It runs fine, but  clock is humming when plugged in. That is a low humming noise heard at the bottom of the clock. If I listen in a quiet room, I can hear the humming. I take this isn't normal?

The voltage of the clock is set to 220v, I wonder if I should set it to 240v, as voltage in Finland is 230v?

    For what it is worth, I would have to say most clocks especially those running off household current,generate noise to some degree. In an otherwise silent room this can be annoying. I would lubricate the "works" as this is most likely mechanical. I would also put some felt where the clock rests against the wall usually at the bottom sometimes the vibration to the wall increses the sound like a sound box in a stringed instrument making it louder than need be.
