Low hum from amp

Hello

I have a low hum coming from my integrated amp.
When I turn up the volume, the hum does not get louder but stays at the same pitch.
Any ideas please as to what's causing this?
Thanks!

"the hum does not get louder but stays at the same pitch."
It stays at the same "amplitude" or level (or volume or loudness) not "pitch".
Pitch is different than loudness.
