Super Regulator
You want to build a preamp, a DAC, a phono stage, anything that needs a nominal supply voltage between 3.3V and 18V or even more, positive and/or negative polarity?
You want a power supply regulator that approaches an ideal DC voltage source as best as possible, bringing out the best in your equipment? Look no further – the Superreg fills your bill beautifully!
The 86 x 77 mm (3.4 x 3 inch) board holds all parts (sourced by you) including a heatsink, for a dual supply regulator that can deliver up to 1A per side. Board can be separated in pos and neg reg board if needed for construction. Several threads on diyaudio discuss customization for a wide range of output voltages. The regulator boards accept a DC input from your favorite transformer/rectifier/reservoir cap.

Details
- V2.3b PCB designed by Jan Didden based on the Jung/Didden regulator from Audio Amateur, includes Walts’ latest refinement;
- Blue PCB contains one positive and one negative regulator; can be separated for individual use, 10mm mounting pitch in both cases;
- Picture shows stuffed board - this is an example only, we are only selling the PCB and you will need to buy all the parts to stuff the board;
- Article including BOM & Schematic by Jan Didden
- BOM for V2.3
- Jan's introduction to the Super Regulator in his blog
- Measurements from Jack Walton's Linear Audio Vol 4 Article.
- Performance graphs from this article regenerated in color. The Super Regulator is marked as "Jung" in these graphs:

- Connection diagram for 2.3b
- 2.3 Update includes:
- added option to use SMD as well as Through-Hole footprint for the opamp
- added an RC-filter for the remote sense to be better armed against tendencies for oscillation
- Voltage settings
- See this post containing a list of resistor values for commonly used voltage settings
- See this PDF on customizing the output voltage
- 2.3b Update includes:
- Updated legend on silkscreen

I completed the positive rail of the super-reg and the result is outstanding. Very happy with the purchase. I use the super-reg to power the DIY 6-24 Biamp crossover.
I had tried at least 3 different linear regulators, including the Salas shunt. They were being used on a Fully differential Class A JFET input buffer. Until i tried this device, I had no idea what I was missing. Wicked dynamics, unreal high frequency definition and superb bass definition were brought out of my system. Jung and Didden gave the DIY community a real gem with this set of boards. Highly recommended! Thanks guys!
Delivery of the boards was quick. I have not yet assembled these yet. In the past, I purchased two of the same version of the super regulator. An informal oscilloscope check of those, powered by a generic 317/337 regulator board, showed a definite decrease in general noise comparing input to output.
This is a very good sounding voltage regulator. Highly recommended.
This regulator makes a dramatic improvement in the sound quality and is the best out of anything I have tried. The boards are very high quality, well designed, and very easy to solder. Thanks to Jan Didden for his expertise and to DIY Audio Store for making this marvel available!
Excellent pcb as always. I'll leave another comment after build the pcb.
You always worry if your goods will arrive when ordering from overseas. They have arrived with no issues. Board feels slick and I will begin building in a few weeks.
Looks excellent. I did not build the project yet
I bought the reg. on behalf the positive posts on DIYAudio.
I did not have a big hope that it will be much beter then other DIY regs. but the it exceeded my all expectation.
It is really so good and I have tried many. It is comparable to the best on the market.
PCB is very proffesional, instruction and the Mr Jung Didden very helpfull.
Recommended for every one who want to try reaally audiophile experience for really attractive price.
I have not built the project yet. The board looks good.
A must for a preamp
Not much to say really. The PCB was as expected. Still to build the device.
This is now ready to be tested in conjunction with an older Danish PreAmp I built from the 1980s when the power part was built into the cabinets themselves. Now the Super Regulator (PSU) together with the transformer will be mounted in an external enclosure. And then I have high expectations for this Super Regulator in this setting.
Being an amateur and a student in electronics college instead of picking a ready built simple cheap Chinese made power regulator I opted to buy the Super Regulator. it definitely has made me learn more how it works in which each individual component does. Excellent learning tool. I’m still learning
This is a super nice reg. I built one for nuhybrid amp and hiss level is greatly reduced! Overall it is very easy to calculate resistor values, the ground resistor R7/14 shares the same voltage as your choice of V-ref. Nice product!
Very good layout and performance.
Many parts called out on BOM are no longer available. Currently available parts seem to have shifted to new standards for PCB hole spacing, etc. Its still a useful circuit for audio, IMHO, but the board and BOM could use some work done to update them.
...require excellent quality PCB's.
Job acheived, a pleasure to build.
Big thanks to Jan Didden for this regulator!
Excellent design and very good performance. I have several of these from different suppliers Andy Weeks / Pilgham Audio etc. Your boards compare very well with any of these others.
Super Regulator
thank team
I was deeply moved by the good result I did not imagine.
I applaud the developers' long-standing research results and generous efforts.
I think I will order several pieces later, thank you for the wonderful PCB! .
Excellent product A+++
Super Regulator Board
Everything ok with diyAudioStore! I’ll buy again for sure from them.
Good job.
I have no complains. Handling went smooth and shipping time was reasonable.
Quick delivery, excellent quality PCB, more info when its built.
Items arrived promptly.
Components ordered from local supplier took much longer!
Pcbs are of good quality. Will start the build soon.
very good thanks!!!
Price for board is 19 dolars.
Is it free shipping to Serbia -Belgrade ?
Hello slobodan. Shipping is NOT free for pcb boards and other products originating from our USA warehouse. Only chassis from Italy include free shipping. Chassis accessories/extras are also charged a minimal shipping fee. More information in our Store Policies (https://diyaudiostore.com/pages/magento-store-policies). Thanks.
