Your power-supply readings are excellent, pretty much identical to mine when I was working on it, before I had the whole set going. The deviations are because the set isn't loading it down until it's working completely. The PS is done correctly. Good work.
Could get a little expensive, smoking 6BG6s. They normally do get very hot though. I guess just keep the tests short until you know it's all correct. Your -71VDC on pin 3 is excellent. Pin 4 isn't used on a 6BG6, so I assume the socket lug for pin 4 is just used as a soldering tab for some other circuit. Without pulling my chassis, I'm not certain what you ought to see there, except that the Sams spec says you're pretty much on track.
Your black screen certainly isn't the brightness control's fault, excellent readings there. The low voltage on pin 10 of the CRT is suspicious. Maybe focus there a bit...?
You're close though.
