PART 3: any relationship with the bias set-point ?
Apart from what I just posted above, I wonder if the filament current is related to the bias set point, or to put it otherwise, if a lower bias setting means a lower filament current in the tubes.
I think the "optimum" bias setting of the KT120 is more "aggressive" (higher) than for a KT88.
IF there is a relation btw bias setting and filament current, I guess that if I follow the instructions of setting the bias of the KT120 at exactly the same level recommended for KT88, I would be biasing the KT120 below their optimum set point then in turn I would have a lower filament current (???).
In that case, it would be again going in the right direction in terms of not over-driving the transformers, the whole set-up would be relatively conservative... isn't it?
