This circuit is from Mullard documentation from 1969. Transistors support current equivalents. Output transistors must be mounted on heat sinks.
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...
