All of the PSU's I've built are using basic 3 terminal regs, 317/337, 79/79xx, etc.
I want to try to improve in this area.
(+15 - 17v territory) 1 amp or so.
Not that there's anything wrong with these psu circuits.....but I'd like to learn/experement a bit further with different (and tighter tolerance) PSU designs
Mostly for Headphone amps, Line Drivers, HiFi preamps....all op amp based.
--------------
Here is what I've come across so far. If you can add to these choices, or recommend one...:
**1970's National PSU design handbook (circuits for adding (dated) op amps along with 3term regs, to create dual tracking supplies.
**CA3130 and CA3140 datasheet schems.

**Sulzer, Borbely, Jung designs.

**Tweaking this to give +15v
