Bias question - EL84 & 12AX7

[BenPerkins]

Hi guys,

I have a Carvin Belair 212 -

4 x GT-EL84R (6BQ5)
4 x Fender 12AX7

If I put in a new set of tubes (exact same models) do I need to rebias? Thank you.

You don't have to
On my Belair . I swapped and increased the bias from the factory 70
To 78

It made the amp a little more "present"
