The fact that the amp hums, suggests extreme incompetence on the part of

I would not be concerned if it were only audible in an otherwise silent
room when you put your ear close to the amp. But in my view it should
certainly be inaudible in such a room when you are sitting in a normal
listening location.

Slainte,
