I had reached out to Vertitron first about 4 years ago and then again about a year and a half ago. Both times I gave them the job number they said "absolutely no support for those controllers"! They never mentioned they still had boards for the VSC controller. I think because these are DC rheostatic and from what I gather they may have only made half a dozen of them they don't want to deal with them any more. Long story longer they have agreed to at least accept the control box in for testing and possible repair but they don't make any guarantees on it being successful. Fingers crossed.
