Help to repair oscilloscope Philips PM3207 (Algemeen)

After all this, the transformer is the remaining suspect.

But the oscillograms are a bit confusing: I'd expect the collector current to clip. But you have a nice sine.
What is the scale (V/div?)

Hopefully someone can help you to a new transformer.
