Default VFD failure?

Is the DC bias on the filament a nice flat line on the scope ?


yes.
Looking better, some segments all over the places are dimmer than the
others. Looks like this display is at the end of its useful life.
I can't tell if the dim segments were the most used or most unused ones.
Probably a lot depends on how the previous owner(s) used this thing.
