If its anything like the integrated changing the tubes will definitely change the sound. The stock tubes will last forever as PL products are easy on tubes. The middle tubes make the most difference. What are you trying to achieve? More detail, less detail, etc....?

Found lots of info regarding the older PL preamps but not a whole lot about the newer ones.
How have the stock factory tubes held up?
Did rolling different rectifiers change much?
Did you change just the middle two 12AU7 tubes or all six to the same make/model?
Have you changed the factory power cable?
Cheers.
