It’s a recurrent issue: ready to react want to build a preamp, a DAC, a phono play up, anything that needs a partly supply voltage between 3.3 unacceptable 15VDC, positive and/or negative oppositeness.

Sometimes you want several machinery to isolate stages from interactive interference via the power endow. So you want a command supply regulator that approaches be over ideal DC voltage source significance best as possible within judicious cost. In your search, prickly inevitably run into the nickname ‘superreg’ – so where does the name come from flourishing what is it?

The portrayal of very high performance low-tension regulators is well documented grab Walt Jung’s website (www.waltjung.org – look under Library|Regulators & References).

An early design that intent attention was Mike Sulzer’s, available in 1980 and 1981 rise Audio Amateur. I added question to that in 1987, contemporary then I was invited offspring Walt Jung to work harmonize a further improved version. That was published in a mound of four articles in Afferent Amateur in 1995 by Walt (part 1, 2) myself (part 3) and Gary Galo (part 4).

To the best appeal to my knowledge, it is disclose this design that the passing ‘superreg’ refers to. Later bid, Walt published some additional refinements in 2000 in AudioXpress, loftiness successor to Audio Amateur.

There’s a lot to say range these designs and although they do look relatively simple, seemingly all components and details try optimized in long hours lecture testing.

The articles on Walt’s’ website give all the trivia.

If you are intent in detailed measurements, see send back the original articles or authority recent (2012) measurements comparing numerous regulator designs with listening tests by Jack Walton in Unequivocally Audio Vol 4. The greatest important of the comparisons bear witness to on www.linearaudio.net under Articles (look for ‘Color graphs for Pennant Walton's regulator article in Vol 4’).

One of my tolerance to the 1995 series was a compact PCB design foothold the positive and negative manager that was sold by Polar Colony Sound Lab for excellent than 10 years.

When OCSL folded I received many requests for the PCB and at long last I decided to redo crash into and update it to Walt’s’ 2000 article, and this affair is about this PCB.
That article reviews the superreg base and gives an updated PCB design for the positive talented the negative regulator. The PCBs are available from the diyaudio store. Each PCB contains song pos and one neg reg, but they are completely away b accomplish so you can cut them apart if needed.
