Amps Experts, can anyone recognize from where the noise out in my DC 5K (video)

[haq]

Hello everyone,

When I raise the gain up more than 1/4, the mp starts to emit humming sounds,

Some people told me this is normal for DC monos !
Can anyone recognize from where & what the noise is?

Yea its normal I was told it makes this noise when you are clipping it. Are you?

Are you just turning the gain up or are you actually using an oscope or dd1 to tune your amp?

I will give you your answer once you answer my question.
