Um.. "at the power transformer"
Don't you mean at the plate of the '27 detector?
What happens with the point E voltage if you pull the '27? If it stays low, then something is lugging it down. There is a cap in the filter block that goes from point E to ground. Is there any chance that cap could be installed backward? (That's assuming you've replaced the original caps with electrolytics.)
