Restoration notes
The motor required cleaning and new lubrication. It has been restored to better than new performance with synthetic lubricant. The acrylic viewing window is in excellent shape. The illumination was a small 80-volt fluorescent blacklight which was starting to flicker from age. It was replaced with a 3-LED blacklight strip along with my own custom-made high voltage AC to low voltage DC converter since LEDs are low-voltage DC only. I make my own as most units that do this create a lot of RF noise which can interrupt radio operation nearby. The alarm was stuck, also from some dried grease, but was restored. It is a mechanical buzzer and it WILL wake you up! BZZZzzzzz......Get up!
