Removing Tubes - Do I need to get it rebiased?

[Scatterwound]

Hi There,

The tubes in an amp need to be removed in order to change the existing speaker. If you remove the power tubes....Change the speaker.....Then replace the tubes in the exact same sockets does the amp need to be rebiased? Or does it depend on the amp?

just drop them back in where they were.

+1 no need to rebias replacing the same tubes.
