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 amplifier uses a 1975 integrated circuit, which is uncommon today. The circuit has a gain of 30...
Using junction FETs, a configurable configuration is achieved for very low frequencies. FETs can...
This 2-terminal regulator was obtained from a 1990s National Semiconductor manual. The components admit...
