This is a simple version of the gyrator circuit that many people are using for thier cd players and pre-amps. It does not require a pre-regulator, as the zener maintains a stable voltage at the output. Further, it can be used for power applications as well, with almost any input / output voltage that is required, as long as the pass transistor can take it! The output voltage should not be any lower than 2v below the voltage of the zener. Additional filtering can be used before the drain of the Jfet, but I have not found this necessary, as the Jfet tends to deliver a clean voltage to C1. A highly effective circuit for both low and high power applications.
The transistor types should be selected to taste...... Don't forget to increase the capacitor voltages as required.
