Assembled S11 SUPER linear regulated power supply board LPS PSU

Description

S11
is a high-performance DIY single-rail linear regulated power supply (PSU). It is basically half the  dual-rail PSU σ22, and possesses the same low-noise, high-current, excellent line/load regulation, wide-bandwidth, and stability characteristics. S22 is ideal for DIY stereo headphone amplifiers, preamplifiers, DACs, network media players, and other applications requiring a single-rail regulated PSU.
The circuit uses all discrete components (no integrated circuits), and features high-current MOSFETs as the output "pass" devices.
S11 is derived from the σ22, which is the result of a community service project for the audiophile hobbyist. The schematic diagram is open source. The circuit design, as well as the printed circuit board layout are the work of AMB with participation from the DIY community. It is designed to be relatively easy to build, but it is not recommended as a first-time project for the beginner.
PCB size:  102X86mm
we can provide   DC5V /  9V /  12V / 15V / 18V / 21V / 24V version for choose.      ( the output voltage can minute adjustment）
Please tell us which version is you need!!
we also can accept custom-make other output voltage.
S11max
Output Current 30A.
The input AC voltage recommned higher 3-5V than the output DC voltage. (for example. if you need DC12V voltage output,  the input AC recommned 15V.)
All the components are using the high end parts. what you see what you get.
