I have, more than once(!), found that my gut feel for "close enough" is not always in fact close enough, and I have to start over with more attention to more details.
In the initial post, you drew attention to a specification for 450v/350v plate to cathode, using 6L6GCs into 6000ohmsCT. But you are measuring something like 415v/350v (after subtracting transformer DCR losses at max power) into 6600 ohms. All these little differences can add up fast ...
My two cents.
