463 ma is reading from where? Is that total taken from AC input?
Tube heaters should be drawing 300ma, if significantly higher then there isn't enough resistance in that line. The 25Z6 should also be supplying around 80ma, so a total of 380-400ma would be in ball park. Even if heater string is high, I doubt it has anything to with popping issue.
