A Shunt-Reg with current source for DAC/Phono needed

[Blitz]

I have build the superreg of Allenwright (for tubes)with a constant current source and a shunt-reg and I like it quite a bit. Now, building a DAC and a Phono-Preamp, I am looking for a similar design which works not only for HV, but as well for 30V or 5 V and giving positive and negative rails.

I have looked around with the search function, but most designs are series regs. As I need only 100-200mA high-quality regged current, I would highly appreciate if the regulator-experts could bring in their knowledge around that.

THX a lot

Maybe you should check The LC audio shunt reg used in the Zapfilter schematic is availble on www.lcaudio.dk

Shuntregulator

Hi Blitz,
You can use the simple design below. Maybe use a somewhat heftier transistor for the CCS. The diode is a red LED.
I keep asking myself: what is the superiority of the shunt regulator above the series regulator???
