Let's get one thing straight here. B+ is not suppose to get to pins 5 and 6 of the 6AQ5 through C50. C50 is a audio signal coupling cap to the top of the volume control. C50's function is to pass the audio signal from the plate of the detector to the audio output grid. A capacitor is used because it's intended to block the B+ feeding the plate of the detector tube from getting into the grid circuit of the 6AQ5.
