During installation of the tubes everything was going fine and testing well. After the 4th or 5th tube, during the testing sequence all the tubes would display both '0' & '1' at the same time. The would stay illuminated for the duration of both numbers and sequence through the rest of the digits in a normal fashion. I thought maybe the board needed a reset, so I continued with the build.
Now I have completed the build, I believe I have the clock set correctly, although I'm still trying to figure out some of the setting. However when ever a tube needs to display either the '0' or the '1' it will display both digits.
I have checked my solder connections, the board for any possible shorts, but have not been able to find any yet.
Any advice on what to do next to fix this?
The clock is suppose to be showing 13:54:23 but as you can see both the '0' & '1' are displayed on the first hour digit.
