PACE ADS200 transformer audible noise

[jako]

Dear community,
I've just bought ADS 200 soldering station and everything seems to be working perfectly.
Just one concern that I have is the audible noise of the transformer, especially when tip is heating up/under load.
It is not loud, but definitely hearable.
Also in some cases after turning on main power switch on I can feel instatnt vibration kick with my hand on the chassis.
My questions for the owners of this station - did you encounter similar transformer behaviour?
I have a 230VAC version.
It is just normal transformer-ish noise, but on the other hand I didn't hear it in the video reviews.

Thanks in advance for any feedback.
Best regards,
Konrad
