Default How to change tubes ??? (NEWBIE)

Hi to everybody.
I have a Music angel with n2 12AU7, n2 12AT7WA and n4 KT88.
I would like to change the first two kind (I have them from Mullard), but I don't know if something can be broken.
Reading the other posts I saw something about the bias. There is a bias for this kinds of tubes too?

Turn the amp off, and pull out the old, plug in the new and play. Small signal tubes (12AU7 etc) are autobias and do not need adjustment.
