Hello!
I bought Ice tube clock kit in your pages 1 week ago and I made it.
But I found out display problem.
It is the problem that LSB is dark like this picture.
This picture is my kits. They have same situation.
So, I checked my kits. But, drive voltage and soldering is correct.
I don't know why LSB is dark.
Display is dark only LSB

This is mentioned in the FAQ. It is due to the way the tube is driven. The DC bias voltage decreases along the length of the tube so the digits at the end are dimmer.
One customer has come up with a nice software hack to address the problem: http://forums.adafruit.com/viewtopic.php?f=41&t=23586&p=130839
