Might you be conflating a lower HT with one that’s more saggy?
I don’t think that’s necessarily the case, (though it might be with the particular PTs here ).
For a given OT load and reservoir and screen grid cap values, as with Marshalls, and for a given HT winding gauge wire, the lower HT should be stiffer.
Nope. Higher B+ = higher preamp voltages = stiffer, brighter, less gain. If you compensate by raising B+ dropper values to keep preamp voltages the same, that's another story. It's the reason why some people use a variac or raise the value of V1 plate resistors to lower plate voltage. That gives you more grit, gain, and a looser feel = "brown sound." And it's the reason some builders, like Cameron, typically shoot for well over 500v B+ to get a more angry, aggressive, tight sound.
