Start at the power supply - make sure the positive sides of C5 and C6 are grounded. The Sams has an error, and shows negatives to ground.
I have to look at a set like this for a long time to figure out how it works. If you're used to mid 50s and newer tube sets, these PS and sweep circuits look truly insane.
