FC Power

Super simple Eurorack power supply based on easily sourced and inexpensive parts.


FC Power works from a 12V/1000mA  AC wallwart and provides ~500mA at +/-12V DC, ~100mA at 5V DC (optional). Dead simple to build and based on easily sourced and inexpensive parts. You can also choose to built it as a +/-15V supply with minor component changes.

PLEASE NOTE: FC POWER works from a 12V AC wallwart. FC Power will not work from a 12V DC wallwart. If only one half of your FC Power is working, the likelyhood is that you are using a 12V DC wallwart instead of a 12V AC wallwart.

You can plug it into a single module for testing purposes, or break out the power to a Doepfer bus board, Tiptop flying bus board, DIYed stripboard bus board, or our own solution, the Expandobus.

Dimensions of the PCB are 110mm x 42mm. Height of a completed unit is 30mm.

The perfect solution for:

  • Bench test supply
  • Small, self contained synth projects
  • Skiffs cases
