We found this circuit in a 1969 General Electric documentation. The circuit uses transistors of the time and the diodes in the dotted board must be mounted on the output transistor heatsinks.
This circuit was suggested by Signetics in 1980s documentation. The circuit makes use of the...
This simple circuit controls the brightness of an LED from LDRs, NTCs, PTCs or other resistive sensors....
This stage for JFETs was found in a 1965 US publication, but is valid for modern components. |...
