    Did you have a number for the output tube idle current before? Has it changed?
    Like Helmholtz said, differences in DCR on primary side could slightly affect idle current.

    The power output of the amp will be mostly determined by the limitations of the power transformer. If you are using the same PT that was in use with that OT, you should be fine.
