During WW2 and years after, a vibrator was common technology used for vacuum tubes high voltage provision in military radio equipment.<\/p>\n\n\n\n
The vibrator is an electromechanical device that was used to convert DC voltage into pulses that could be converted to higher voltage using a transformer, rectified, filtered and used as high voltage supply for vacuum tubes.<\/p>\n\n\n\n
A synchronous vibrator had an extra set of contacts that took the place of the rectifier and were used as a electro-mechanical rectifier.<\/p>\n\n\n\n
Various vibrators were used by the Haganah Signal Service and by the IDF during the War of Independence (1948), the Sinai Campaign (1956) and the Six Day War (1967).<\/p>\n\n\n\n
