Um - let's make sure I understand this correctly - current is limited
by the fuse on each individual leg. *BUT* the amount of current
relative to the individual devices is unlimited, the fuse being the
actual controlling factor? That makes more sense - But if the filament
winding is sufficiently robust (and it should be in a well-designed
transformer), would this not be essentially the same condition - the
tube filament (heater) becoming the de-facto fuse?
Now, something that would exceed the current capacity of a transformer
winding sufficiently to cause individual tubes to behave differently
based on differents in filament draw (but still within "normal"
operating specifications for each tube) should be a remarkably rare
condition - again assuming a properly designed transformer?
