Описание: This clock uses telephone exchange uniselectors (stepping switches) to display the time on 6 nixie tubes. The dekatron is part of the 1 pulse per second timing system derived from the mains frequency using vacuum tubes. It's too noisy to run all the time but looks terrific when it's going!
