535 at node A doesn't sound bad. I've had V4s range from 535 to 545. you can check the AC voltage from the wall too. you might feel better if the AC voltage is a little low too.
Point B is never a full 10 volts less than A, even if you measured 540 at point A you would likely measure 539 at point B.
point C is high compared to the schematic, but again, I'm not worried about it.
Lets clarify what you mean when you say it breaks up "early". are you saying that it breaks up a really low volumes, or are you saying that it breaks up when you have the volume control set at 11 o'clock and while its loud as hell, you don't expect it to break up when the volume control is set so low?
is it a pleasant breakup? or does it sound like its farting out?
another question : do you have an oscilloscope?
