KEF PSW2000 Woofer - Relay clicking issue.
« on: September 26, 2017,11:44:39 »
Hi folks,

Had one in today for this common problem, and checked about where seems C52(47/63) is the usual culprit as it dries out.

Replacing was easier than I thought - Just remove the 4 screws at the front securing the module with heat sink, and tilt upwards where the cap can be got to and replaced with the board edge on.

ESR checked C52 and found it totally O/C, so replaced with 47/100 as guess it died of ripple current even though it's only 50/100 Hz through the toroidal mains tranny - Chris.
