One more interesting circuit.
Connect power of OpAmp to output positive and negative line of reg.

Every time I simulate it, it oscillates. I'd like to see a Bode plot from 10Hz to 10MHz. Consider some R between the collector of Q6 and ground (this has been mentioned before.)

With respect to PA's comment -- the faster the opamp, the lower the output impedance of the circuit.

..Though there's no use using a faster/slicker/more-fashionable opamp if you cannot stabilise the whole and keep it that way into the real-world load it drives (over the full range of expected load currents)...

Agreed, we found that the AD825 sounded really nice in the "Improved" Jung regulator. Most of the time I've used the AD797AN in the "Original" (1995) regulator without problems, but sometimes it can get finicky. LME49710 sounded well and tested well.

Hi Guys just read the article in linear audio about the different regulators.

Is there any way to get my hands on a PCB for the Jung/Didden regulator or evt. the Sjöstrom regulator. Preferably the first one. I'm looking for a +/- PSU of my audio path opamps. I was aming at the best avail. Any tip or link would be much appriciated.

TIA,

Peter.

The old colony boards are no longer available. Per Anders has a website -- and designed the Sjostrom boards.

Has anyone built and measured a Bobken regulator?

Default Superreg boards

I finally bit the bullet and layed out a set of superreg boards based on the original 1995 series articles, updated after Walt's 4/2000 article.
These are the successor boards to the ones Jack showed here.
All info is here: The Superregs

Let me know if there's anything I missed or got wrong.

Looks nice, thanks for the files.

Just wondering if you could split the pos and neg boards? Most of the time I only need the pos one, would be great to have separate boards so that we could just choose what we need.
