Dim Glows
Another occasional fault is that the selected position is not very
bright. This tube has a remarkably dim '9'. It is still visible and
brighter than the '8' and '7' additional lines. Therefore I use this
tube in one of the 10's positions, for example 10's of hours, so
the '9' is not used much. I do have the odd tube where the
wanted line and the spurious lines are more or less the same
brightness. I would use this tube in a units of seconds position
so it changes every second, then the eye sees it steps through
the sequence '3' … '3' & '4' … '5' and you can then read the '4'
position correctly.
Burns
Look at position '6' - there is a black line showing the phosphor
has been burned by the tube. This indicates that the tube has
been left glowing in that position for a long time. This tube was
sold as NOS but it is most clearly not!
Stuck Tube
The occasional tube is just plain stuck and won’t budge
whatsoever . Here’s an E1T that just displays multiple lines with
no movement. Who knows why . Clearly not of much use in a
timepiece ..
