That's correct.

It could be an adjustment, or a symptom of another problem.
An open (or absent) electrolytic (C1) on the cathode of the output stage will cause severe non-linearity with insufficient sweep at the bottom. I'm wondering too if the problem isn't related to T2 (the coupling xfmr.) being different from the original.. and also if this difference is gonna cause the vert. frequency to be off. oc
