It seems there could be a risk of excess filament current if the "wrong"
filament pin is selected. To minimize the risk of this, both filament pins
can be connected together and the "zapper" connects from there to the grid.

Between ONE of the filament pins and the grid! Across the filament would
of course destroy it.
My experience with these tubes has been that it's common to see a short
that develops only
after the filament warms up. In this case, you wouldn't be able to do this
with a cold tube.
