Figure 2: Walt Jung/Jan Didden regulator’s instability is shown. The top trace = Vout, the bottom represents the output load current of the regulator. Figure 3: John Roberts' design is a dual-polarity tracking super regulator where the negative half establishes a regulated output and the positive half follows by inverting it.

Walter G. Jung 2015 (www.waltjung.org) still provide excellent results. An input RFI filter is used before M4, preferably with a low inductance capacitor type for C1. Some subtle but important changes within the regulator and shunt driver have been made, vis-a-vis the AudioXpress version as cited above. The small value emitter

Jung Super Regulator. Finally we come to the Jung regulator. In the first two issues of TAA in 1995, Jung describes his circuit and gives some very detailed test results of it vs. several other linear regulator types. In issue 3, Jan Didden gives a PCB layout for the circuit and gives some advice for applying the regulator circuit.
