Just to note the voltages on the 6ah6 are the same when feeding the video into the tube and they read the same at both ends of the contrast control .
Problem has to be before or at the 12au7 because that's where the picture and sound splits and there's no sound , only sound that can be heard is a buzz in the audio when contrast is at full and there's a slight overload on the screen plus way to black.
