This simple 6 V source stabilized by zener diode was found in a European technical publication from 1972, but it is current for its simplicity and the components it uses.
We found this circuit in a 1977 Radio Shack manual. The light bands are given by the operating gain...
The circuit in the figure is a current regulator with adjustment in the range of 0 to 3 amps. The...
This stage for JFETs was found in a 1965 US publication, but is valid for modern components. |...
