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
