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 published in a 1979 magazine, but it can still be easily assembled as the...
This circuit was found in a documentation of the 80's having characteristics of high overvoltage given by...
Here we show how a Constant Current Source can be created in the Multisim Blue using a common BJT...
