@z28g2000prd.googlegroups.com:

These VFDs typically want +30v for the anode,

IME, the filments are grounded, with the segments pulled to ground ot -30
as needed.

and filament v depends
on the display, but is very low. They can dim after 20 or more years
of use, if its that old I'd suggest a slight filament boost. One way
is to put a turn or 2 onto the mains transformer secondary and connect
this in series with the filament feed.


If the trasnformer is open framed.
