This video is about my kef kube-2 repair. Note that I have already ordered a new plate amp. It's a tough call as to whether to do this repair, the plate amp is half the cost of replacement. However, while they are currently still available (not much longer no doubt) it's certainly cheaper than shelling out $1200 for a new sub when the woofer in this one at least still works perfectly. I have tested it and it is fine.
If the board was not charred this could of been repaired, and given that it's basically been left powered on non stop for the past 8 years i wanted to avoid risks of further issues by replacing the entire assembly rather than just the power board. (considerably cheaper option) The input/control board above the power board would of been subjected to considerable heat over its lifetime too and has been known to cause issues as well.
The exploded component and track is on the secondary side of the power supply and appears to be leading towards the amplifier IC. Something will be dead shorted or failed. I may check a few components before throwing it in the bin to see if i can tell, if i have time.
