JC Auto does electro luminescent light power supply units. Rebuilds or sells what he has in stock. He advertises in Hemmings. I've used him to re-do the power units as well as my dash ighting.
Thanks - appreciate it. Maybe I will see you at Hemmings Concours at Lake George in Sept. Bring my 1966 mauve hemi charger for the Sunday show. I f you will be there stop by and say hello.
