PASS F5 Clone-Question

I have a Pass F5 clone that I really like a lot. I do have a question about it. My amp has a slight , but discernable humming sound when it is turned on. It is almost like a transformer hum. It is not audible through the speakers. Is this normal or an indication that something is wrong with this amp?
