In any event you're no longer focusing on the audio output issue and the point feeding R54 has no influence on the audio output portion.

The top-side of R56 is connected to the bottom side of R54 which is connected across C3B, which is the point where you were saying that there was a "dead short" earlier when I was telling you that the voltage from there was going from 145V to 22V at pins 5 and 6 on the 5AQ5 tube socket, which by the way, that is how the original C3B in the can was hooked up from the factory, unless you're trying to suggest that somehow this TV was miswired from the factory and somehow managed to get past Zenith's stringent QC standards?
