High B+ and low B- would indicate some circuits aren't pulling enough current. As B+ current increases you'll see more voltage dropped across those B- series resistors between the center tap and ground. B- will become more negative and B+ will become less positive. The reason that happens is because as the tubes conduct more they become a greater load on the B+
