.....and you know the filament would NOT have failed anyway

Sometimes, like it or not, things just fail because they
have a manufacturing defect. That sometimes triggers us into
finding a pathological cure.
That's certainly OK so long as we know we are leaping to
conclusions. :-)
Of course it is a good idea to not use a transformer and
wiring that can dump 100 amperes into a 10 amp filament, the
question is what really caused the failure.
