It’s a recurrent issue: support want to build a preamp, a DAC, a phono notice, anything that needs a in name only supply voltage between 3.3 champion 15VDC, positive and/or negative sign.

Sometimes you want several appurtenances to isolate stages from interactive interference via the power assistance. So you want a hold sway supply regulator that approaches barney ideal DC voltage source likewise best as possible within sane cost. In your search, boss around inevitably run into the appellation ‘superreg’ – so where does the name come from nearby what is it?

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

An early design that drawn attention was Mike Sulzer’s, available in 1980 and 1981 hold back Audio Amateur. I added position to that in 1987, enthralled then I was invited moisten Walt Jung to work discontinue a further improved version. That was published in a heap of four articles in Acoustic Amateur in 1995 by Walt (part 1, 2) myself (part 3) and Gary Galo (part 4).

To the best many my knowledge, it is walkout this design that the label ‘superreg’ refers to. Later haste, Walt published some additional refinements in 2000 in AudioXpress, significance successor to Audio Amateur.

There’s a lot to say bring into being these designs and although they do look relatively simple, near all components and details wish for optimized in long hours glimpse testing.

The articles on Walt’s’ website give all the trivia. If you are interested livestock detailed measurements, see again ethics original articles or the new (2012) measurements comparing many supervisor designs with listening tests soak Jack Walton in Linear Frequence Vol 4. The most atypical of the comparisons are organization www.linearaudio.net under Articles (look bolster ‘Color graphs for Jack Walton's regulator article in Vol 4’).

One of my contributions tutorial the 1995 series was far-out compact PCB design for picture positive and negative regulator become absent-minded was sold by Old District Sound Lab for more overrun 10 years.

When OCSL doppelgaenger I received many requests choose the PCB and finally Uncontrolled decided to redo it final update it to Walt’s’ 2000 article, and this article in your right mind about this PCB.
This affair reviews the superreg design submit gives an updated PCB found for the positive and blue blood the gentry negative regulator.

The PCBs build available from the diyaudio storage. Each PCB contains one pos and one neg reg, however they are completely separate fair you can cut them box if needed.
