Jolida 302B audible hum


Hi, I can hear a relatively big hum from my speakers everytime my refrigerator (not far away from my system) starts. This had never been happened on my previous SS amplifier. Is this one of the natures of tube amplifier? Does it help to upgrade the Jolida power cord?
Thousands of thanks.

Are both on the same circuit? Do you have a dedicated line for your equipment?
