  1. Hi I was looking for a straight up BOM for the +/- 12v PSU for the AOUT board, but i can't seem to find any, so i am trying to gather the components for myself based on the center-tap transformer mode http://www.midibox.org/dokuwiki/doku.php?id=bipolar_12v_psu#center_tap_transformer I was thinking this setup: Transformer: http://www.reichelt.de/Transformers-PCB-5-0-8-0-VA/EI-42-14-8-215/3/index.html?&ACTION=3&LA=5&ARTICLE=27411&GROUPID=3316&artnr=EI+42%2F14%2C8+215 Rectifier: http://www.reichelt.de/Rectifiers/B40C800DIP/3/index.html?&ACTION=3&LA=5&ARTICLE=4639&GROUPID=2998&artnr=B40C800DIP 7812 and 7912 (pos/neg 12v) But the caps i am a little confused about - in the guide it says a general rule is 470 uF per 0.1 ampere - the transformer will provide 2x167mA - Meaning something lik 2x470uF on both sides, so around 1000 uF caps - and here i need 1 electrolytic and 1 cheramic for pos and neg side before and after the 7812/7912 - correct? To sum it up: 4 x http://www.reichelt.de/Electrolyte-Capacitors-105-C-1000-5000h/RAD-FC-1-200-16/3/index.html?&ACTION=3&LA=2&ARTICLE=84701&GROUPID=4000&artnr=RAD+FC+1.200%2F16 and then 4 x cheramic/film non-polarity? I can't find any on reichelt with the right specs, they are all in pF which seems like to little (http://www.reichelt.de/Ceramic-Capacitors/2/index.html?&ACTION=2&LA=2&PROFID=256&GROUPID=3159&SHOW=1).. Hope it makes sense - i am just a little confused with the cap values actually? Thanks! :smile:
