So I took my old neon tube to the sign shop and it lights up there when they use their wall transformer.

I had already purchased a new 12V transformer and tried it, but it did not make a difference in my CV. So anyone have any suggestions?

Is it possible my tube is old so it needs more power to the electrode and the big wall transformer can supply it as opposed to the little transformer that is used in CV?  

sell it to Necro and be done with the nightmare  

That's easy thing to do, to give up, but those words are not in my dictionary. I will figure it out, just like all the other issues on this pin!! !!

Since I got no suggestions, I took out the oscilloscope last night and traced the issue back to the power board. The circuit seems to work properly when it is not plugged into the primary of the transformer, 12V appears and shut off at the proper times.
But with the scope I can see that the voltage drops significantly when plugged into the primary of the transformer, so that is why the neon will not light. It must be the ULN2003A driver on the power board. Will have to order some today and hopefully that is the end of this issue. There will be no sale to Necro.

I will not need a new neon afterall, mine current one turns out to be green in color.
