0V is at DC measure.
Follow dotted line and find fig.9 scope signal, that is AC on pin 9 PCL805

But there is way more to the left of that tube.
Apparently the sawtooth at pin 3, cathode triode PCL805 is not ok.

So trace back till TS422 (BC158) where it all starts.

Without a scoop , it is only some try and find an error by luck.
