a bunch of posts below gusser commented how MV tubes had less "sag" that other rectifiers and I responded they don't have any sag but a constant voltage drop. Having never seen Vf vs. current plots I wasted a few minutes creating a crude set.
So the voltage drop doesn't appear to be a precisely fixed voltage but i have to say it seems to be pretty constant. This leads me to question how to "qualify" the voltage drop across a MV tube. Since it is close to constant over a pretty wide range of current I want to say it has low to almost no impedance and the voltage drop is just that... a fixed drop, does this mean it just gets put in the loss column and forgot about?
Up next tungars :-)
