Here is the HB-3 entry:

It's another one of those damn TV sweep tubes, which folks have pressed
into RF service. They are nearly unobtainable because the bootleg CB
guys have blown so many of them up.

There is no drop-in replacement, although I have seen equipment designed
for use with sweep tubes modified to take 6146s. The Svetlana EL-509
is probably as close as it comes and it will take some modification to
make those work in most circuits.
