I made a spreadsheet for this purpose. Enter the green fields. It gives you two options, If R6 is known or if R7 is known.

You might need to copy it and paste into your own spreadsheet since the sheet is read only. Perhaps someone can confirm my math so I'm not spreading misinformation.

b4bz,
Your version of spreadsheet is "view only"
copying that spreadsheet did not make it work for me
glennjarrett,
To get 24v I did the following:
D5 change from LM329 to LM4040-10
24V - 10V = 14v
14/10 = "Z"= 1.4
"Z" multiplied by R7 or R14 value = R6/R13 value
for
R7/R14 = 1K
R6/R13 = 1.4K
D2(pos) and D7(neg): change the zener from 6.8v to a 12volt
change to 35v caps
input of superreg needs to be 27vdc

Ok, so a novice question, guys. But bear with me! I am making Wayne’s linestage with Gaz’s Whammy-based PSU. I wanna regulate too, and have the supperreg boards. As a new Mouser basket is coming to an end, I reached a decision point: order or not order parts to stuff the superregs.
If I have a PSU that puts out 18Vdc at the rails, can I still use the values from Hikari1? In other words, what effect does the input voltage have on the output voltage of the superreg?
Haven’t found this in Jans article, but either it is there and I missed it, or it is such basic physics it is not mentioned as it should be redundant. But hey, I am a novice, so here it goes.
Cheers,
Andy
I use the 4A version in Hiraga Le Monstre amplifier. It is necessary to increase the current through Q1 so that Qizl has enough base current for 4A, depending on the choice of Qizl the current through Q1 can be up to 40-50mA or more.
Another transistor Q2 should also be added.

Hello,
I built a single rail 24v Superreg, but getting 24.8v, with NO LOAD. Did I make a mistake with my calculations or do I need to put a LOAD?
Powering the Superreg with exactly 27vdc.
My math:
To get 24v I did the following:
D5 change from LM329 to LM4040-10
24V - 10V = 14v
14/10 = "Z"= 1.4
"Z" multiplied by R7 or R14 value = R6/R13 value
for
R7/R14 = 1K
R6/R13 = 1.4K
D2(pos) and D7(neg): change the zener from 6.8v to a 12volt
thanks!

is the CCS really essential for the OP amp? I have seen somwhere a version, with pass transistor a PNP instead of NPN for positive rail, where op-amp was sinking current directly from the base of PNP. What is the benefit of having a CCS there?
(i`m trying to build symmetrical 18V+-, for 2,5A quiescent current, and predicted 0,2A-3,1A current swing). Pass transistor has around 120 beta.
(i`m trying to build symmetrical 18V+-, for 2,5A quiescent current, and predicted 0,2A-3,1A current swing). Pass transistor has around 120 beta.
original schematic is designed for about 200mA. I need 2500 mA Iq, and 3200mA max swing. I had to tinker with the schematic anyway.
I read about best possible Voltage References, i.e. "ultra low noise" from Mouser.com, as well as discrete solutions from Walt Jung based on 6,2 Zener, and also generally about noise in LED depending on bias current.
It seems to me, that VoltRef does not appreciate too much bias current, so i decided to go just a safe distance from regulation knee at 660 uA. Am i wrong?
