@dan,
@pete, agreed!
The fact that this was a rather simple repair, and that it was only caps, gives me more confidence in JL Audio subs! I will continue to be a customer when it is time to upgrade or expand into 2.2. I would have thought the actual moving driver would fail first but fortunately it is still kicking.
FWIW, the date on the box for this sub is 2009. I got it used in 2014, and its use is regular / near daily at low to moderate volume. So like Dan, it has served me well for many years and I also leave its power setting on Auto.
Makes me wonder why only the power supply caps needed replacement. Is it because of the 85C specification?
Like others have noted, caps don’t last forever. I’d be willing to change out all of the caps now that I have seen how easy it is to change two.
