    2 part question:
    If purchasing a gain matched set of tubes, is a bias on this amp necessary?
    Also, is it recommended to replace the v7 phase splitter tube at the same time?
    Thank you for your help here.

    Rebias the amp it's really necessary. Replace V7 it's not a mandatory but it's a good advice.
