This is a classic symmetrical power supply design with C-L-C smoothing and LM317/LM337 voltage regulators. It can be used for all kinds of low-power audio circuits. Depending on the cooling and the inductors, it can provide up to 1A current. However I recommend to use it for lower-power circuits up to 400mA. This should be enough for almost any audio circuit except power stages.
The circuit is an open hardware design. You can download the design files from GitHub and modify it if you like.

Do you have the parts list? Can I use it with the platINA? How much different would it be from the dual shunt + smoothing solution? Thanks!
