As suggested, I am re posting here. Original post here: Emotiva XPA-2 - ALL caps leaking?
I've just opened the top of my XPA-2 and had a huge surprise: it seems like almost ALL of the caps are leaking from the bottom. Not just the main PSU caps, but smaller ones on PSU PCB and also on amp PCBs look suspicious. It seems like smaller caps are glued to the pcb, like a kind of silicone or rubber to the touch, although it is really just a thin layer. I really can't say if that is glue or leaked electrolyte.
Just a few of the mian PSU caps are a bit bulged on top, but no other that I can see without dismounting the whole thing. I really can't see how they are seated, since I have no view of their bottom.
Even jumpers seem "rusted"!!! Funny thing is, the 2 "rusted" jumpers are on each of the 2 amp PCBs and are in perfect symmetry to each other. Thought maybe originally they had some kind of insulation and got damaged during assembly, but it is unlikely.
This unit has never been exposed to any kind of excessive heat. It has been, however, under my integra DTR40.2 for about one yr, but there is over an inch between them, and XPA's case or top was never hot.
This XPA powers my pair pf Philharmonic 3's and sound is absolutely perfect. No difference or complain at all, high or low volume.
I bought this unit precisely 3 yrs ago, so it is still under warranty. However, I am far from USA right now, and shipping a package this size would cost a loooooot of money.
I work with electronics and I have never seen all caps bad like this, except during cap plague, which I believe is finished and on equipment exposed to excessive heat. What do you think, have you seen something like this before?
Do you agree they have leaked?? Could some of that be actually glue?
I want to hear your opinion before getting to Emotiva.
