Kevin, The tube on the broken cold light should be replaceable. I would imagine that if you were to check with Aristo Grid Lamp Products that they will be able to supply you with replacement tube. In lieu of that Calumet purchased Zone VI some years ago and they should be able to direct you to a replacement.

I have the old Zone VI newsletters and should have one that covers the actual stabilizer operation if that would help. It would take some time spent in searching for me to find it though.
The VC head should be straightforward. There should be a change of light color as the contrast is adjusted from high to low contrast. The high contrast light color should be blue in color and the low contrast green in color. If you fail to realize that then one of the tubes may have failed.
This will take some sorting out but probably not an absolute bust. I don't know what you paid for all of this but I paid something over $200 for the stabilizer used by itself. If you don't want to deal with it then give it all back to the seller and ask for your money back.
