According to the circuit diagram, the 163V supply should be on PIN1 of L2. The heater supply goes to pin 3L2 & 4L2.
The heater supply is high frequency pulses, not smooth DC, so you won't get any meaningful results trying to measure it with a meter!
I'm still not convinced the line O/P stage is doing anything! The three main supply rails produced by the LOPT are the 163V on C2470. 13V on C2443. & 26V on C2453.
If you measure all three, that will indicate what's going on. Depending on the results, depends on where we go next!
