[time-nuts] HP 53131A display dim

The biggest cause of failure with VFD's that I have seen
is the filament voltage drops too low. Usually it is a bad
capacitor in the supply, or a drifting resistor on the regulator.
I have a VFD on an alarm clock made by GE back in 1980 that
has been running 24/7 since it was bought, and is still way too
bright. I make my wife prop something to block it so that it
doesn't keep me awake.
