"By looking at the remains of the filament in one of these damaged
tubes I don't see any white oxide color on these thin tungsten
needles. Can anyone out there establish for certain whether these
are straight, unthoriated tungsten filaments? I guess I could tell
from the filament color but I haven't plugged one of these jewels in
yet. "
Regular thoriated tungsten.
