Good result but maybe not good enough, 10% imbalance is more or less the same as 10% 2nd order distortion or -20dB, in a push pull stage I would look for at least -40dB or 1% which then calls for less than 1% unbalance for all loads.
As I described earlier my own amp has -55dB with 8 ohm and about -50dB with 4 ohm but then I also tune the phase splitter by adjusting one of the resistors, as I don't use matched output tubes it is necessary, without tuning the phase splitter I easily get -40dB or 1% 2nd order distortion.
