Jan, have you removed these from the website now?

Thanks Mark

Had the Super Regulator running for a couple days and happy with the results. Its taken an already very good B1 buffer up a few notches.

Thanks Jan, Walt and the Gang here at diyaudio.com!

They all seem to be there, except for the teaser image, here at my place.
Will take a look at it.

@Jan

Why does the positive regulator use the lower beta range BC556(A)P and the negative regulator use the medium beta range BC546(B)P?

Never mind. I see it's answered at the begining.

Hi...

I just ordered the super regulator boards...I will run one of them at 5 volts out.

From my readings...the voltage reference which is shown as lm329 or 6.9v should be changed to an lm 4040 2.5 volt reference.

Then there is d2 which is a 6.8v zener...It looks like this should be changed to a 2.5v zener or perhaps two red leds in series...

Do I understand correctly?...thanks

AN and Jan discuss the 5v option explicitly, archived on Walt`s website

So, this is what I did: 5V in 5 moves

1) D5 & D10 LM4040AIZ-2.5/NOPB
2) R5 & R12 2.5 k
3) R2 & R9 5k
4) U1 & U2 AD817
5) D2 & D7 Replace with two red led in opposite direction of the zener in the schematic

According to my understanding the reasoning is the folloiwing:

1) To have a lower voltage reference
2) To have enought current through D5 and D10
3) To have enought current through D1 and D6
4) You need an opamp that can work with a single 5V rail
5) You need the output of the opamp to be around 3.1V as explained in post #498

I had to put a 10k resistor in parallel with R6 and R13 to get closer to 5V, otherwise I had 5.2 V.

Enjoy,

Davide

Great...thanks so much...my order will reflect your post...

I did go over to Walt Jung's website as directed by Jackinnj and read Gary Galo's Audio Amateur Magazine articles on the superregulator ...and I see that I shall have to study them a bit...

Supply and Demand

Jan
Thanks for putting these boards out there
Waiting for more stock to arrive
Any E.T.A. ??


Also curious as to why the ground plane was omitted from current version


Thx

I'm not involved in any way in the provision or ordering of these boards, I just gave my updated design to the diyaudio powers.

I deleted the gnd plane because I wanted to control the run of the currents through tracks rather than guessing where they would be on the ground plane.
I thought about using a gnd plane connected to a single gnd point, sort of like an electrostatic shield, but I doubt that it would do anything for audio, while it had the danger of introducing unwanted capacitance between nodes and ground.

Nothing wrong with your reasoning. I probably would have chosen a 4040-5 V ref, and bridge one of the feedback resistors, but that's just personal choice.

Does anybody know why I cannot access the links in the first post or on the shop product page?
I have bought boards some time ago but did not download the info yet

 

[peranders]

The Diy Audio Store ->Circuits boards -> Super Regulator (that wasn't too hard to find )

 

[noSmoking]

AlbertNL,
What version boards do you have,ALL of the info is in these threads.The latest are V2.2.
Here's a link http://www.diyaudio.com/store/amplifier-circuit-boards/super-regulator-v22.html

Finding the product page was not the problem but none of the links on that page work. Try it. See what happens when you click on the links ...

I think I have v2.2 but will check the boards tonight.

The probkem is broken links. Try the links. I get page not found when I try the linear audio article.
Try the other links.
