manekinen @ mdiy.pl builds a simple symmetrical power supply based on LM317 and LM337. Design is Eagle and includes PCB so you can build it your own.
This time, simple project that i made from simple need. Simple, cheap and functional regulated power supply 1,25V to 15V, two separately regulated positive lines and two negative. This power supply uses LM317 and LM337 integrated circuit stabilizers – or their stronger versions. Galvanically separated lines can be connected in various configurations.
