Six VFD tubes (IV-3) in a row

Work on old display technology continues. I spent few nights trying to align six VFD tubes on a piece of veroboard. The result looks neat but very hard to keep proper alignment when soldering 10 pins per tube.

So I dropped the idea of using veroboard and, given the very cheap prices for prototype PCBs, I will try to design one myself.

Originally I wanted to draw many single-tube boards, but I will probably go for a full board that includes driver transistor arrays (ULN2003).

A local OM will help me producing the files for the PCB factory, so hopefully I will save a little time on that step.
