I am not sure where to start with troubleshooting this, so hopefully you can guide me in the right direction.
Test 1 gives 9.87 and 5..82 (and slightly rising)
Test 2 gives 10.57 (with the chip inserted)

Re: Ice Tube clock not lighting
These numbers sound suspiciously high. Make sure that your meter has fresh batteries and check it against a reliable source voltage.Test 1 gives 9.87 and 5..82 (and slightly rising)
What does it read without the VFD chip inserted?Test 2 gives 10.57 (with the chip inserted)

Re: Ice Tube clock not lighting
Replaced the battery, good call
Got 9.11 and 5.02 on test 1/
Got 11.43 without VFD chip on the right side of the Diode. Seems when I did the test while building I got the proper voltage? Which component is likely wrong/broken/mis-soldered?
Thanks so much for your help!

Re: Ice Tube clock not lighting
Sounds like you are getting some boost, but not as much as you should. Check the soldering on all the boost components: L1, Q2, D3, C5, C6, C7.

You might want to start with these. They look a little iffy in the picture:
