MC275 Tube Rolling...

I would love to roll some tubes with my MC275 (the current production version V) It is highly appreciated if all you who are experienced drop a few lines... I would like to know about the tubes that you have ever rolled on this machine from the beginning until the end, the sound characteristic for the each of them and the one which you settled down with and of course... why the choice... Yeah, I am clueless of what tube to get since there are so many out there... All your inputs will be extremely valuable to me. Thank You So Much!

Thanks for such an interesting comment! I've a MC275 MKV and I would like to retube it. Now, my main concern regards bias, as I've been told that electric parameters between valves can change significantly. In a nutshell, I would love to replace factory tubes with Genalex 12AX7 and 12AT7 and Genalex KT88 or Shuguang Treasure KT88 or Tungsol 6550 instead of factory KT88, but I'm quite scared of potential bias consequences if it can cause any harm to my beloved Mc.
Could you kindly give me some suggestion or assurance before deciding what to do as you seems much more expert than me....
Many thanks
