Analog Heat power supply buzz

Hello,

I’ve recently got a new analog heat and noticed a subtle buzz in the power supply when the unit is turned off. If I switch analog heat on the buzz stops.
Has anyone experienced something like that even with other elektron gear ?
I’m thinking in buying a new power supply from elektron site.
Also, the unit is heating a bit more than other gear I have. I read on some forums that is nothing to worry about.

Thanks
