Projects > Whistle Rock Audio ML12 PSU
The ML12 is a four-rail power supply that provides +/- voltage, +48 for phantom power, and an extra + rail for LEDs, etc. The PSU was originally designed for an API 312-like preamp project, but the multiple rails and adjustable voltages could be put to many uses.
