Small PSU PCB

...what a lame name, I was gonna call it 'hard candy' but can't be bothered. It was designed to power stand-alone Null-A panels.
Anyway, its about a simple PSU as you can get. Runs on 7812 and 7912 to give +/-12V. If you bolt them to a nice big heatsink, you could even get 1A per rail (using 1.5A spec'd regulators).

This PSU is powered by a 12VAC wallwart, so no need to wire any mains voltages.

The design is a slimmed down version of a PSU we use in the WAMod workshops, the only differences are:
  • only 1 eurorack connector instead of 7 
  • no 5V section
  • holes for installing spade connectors
so keeping these differences in mind please refer to the WAMod PSU build guide when putting this together.

USD8 each
