That's an old pic from April 2010 that I never posted. I made this back when I loved seeing ballasts operating. I still like it, although it doesn't obsess me anymore LOL.
The ballast pictured is one of my most recent ones, it came from a cooking range dated 1996. The ballast itself is dated 11/95.
