Found in a 1965 Electronic Design, this circuit divides the frequency of a cascaded signal using unijunction transistors. The bipolar transistor supports an equivalent. The shock is 470 mH.
This circuit produces a signal at a frequency of 455 kHz, based on a ceramic resonator CSA455E, by...
This simple unijunction circuit is from a Radio Electronics from July 1963. It can be assembled with a...
Hughes suggests this circuit in a 1968 documentation. The circuit uses old transistors that can be...
