The electrolytic capacitors in the Behringer X32 Rack mixer's power supply are a common failure point for an otherwise reliable console. This guide assumes knowledge of soldering and desoldering through-hole components and the competency to open the mixer and identify and remove the power supply safely.
Tips and Tricks[edit | edit source]
The mains AC wires that connect to the power supply through spade connectors use locking spade connectors. Do not simply pull harder to release these. Pull back the clear insulators from over the spade connectors to access the release tabs with a small flat screwdriver and you'll easily be able to unplug the AC wires.
C8 is a large capacitor, glued to the board. The glue cannot easily be accessed with a knife without removing other components in the way. One suggestion, used by the original author of this guide, is to use a "bent tip" on the soldering iron to melt the glue while pulling up on the capacitor after its leads have been desoldered.
Ordering Replacement Capacitors[edit | edit source]
The following table provides the necessary information to order new electrolytic capacitors for the power supply. Select the highest temperature rating and best (lowest) ESR available when possible. The physical measurements given are nominal and suitable for searching on an electronic components supplier site such as Mouser or Digikey.
