The National Audio Timer, Model TE903, is an early generation digital (segmented LED display) clock/timer made in the early 1970's by Matsushita Electronics of Japan. It allows the switching on and off of a 120VAC output and was intended for use in powering hi-fi stereos which were big at the time. It was switchable for 50/60 cycles and had a European style female recepticle to provide switched voltage. A very good and accurate clock.
