Back in the 1970s, I was living in and old two-story brown-shingle house in Berkeley, CA. The house, which had survived the big 1906 earthquake, was built in 1903, I think right about the time those crafty Germans were building that Teck 1. One day, the bulb at the top of the inside stairs burned out. I climbed up a step ladder with a spare bulb, and removed the white globe cover. Well...the light bulb socket was one that hadn't been manufactured for 50 years at that point. To change the bulb, I had to replace the fixture. It's like looking for an A-cell or B-cell battery. Take care with that baby, Randy.
