UCC/NCC LXZ series
Panasonic FC series (is FR the newer non-aqueous low impedance series?)
Nichicon PW or PA series
Rubycon YXF
These brands' long-life aqueous series are all excellent, but aqueous parts tolerate ambient heat a little less well, and these series' lower impedance is of no special benefit.
So go with best price and availability of the series listed above, IMO.

My neighbour has a friend who is willing to replace all of my caps free of charge with Rubycons YXG series caps (they are the only ones they have at his work). My apologies as I am a complete noob - and cannot fully understand the data sheets of the caps.
smg specs:

the high and low frequency ripple currents appear to have significant differences in values between the SMG and YXG caps. Will it be an issue with stability or cause any issues if I replace all of the smg caps for the rubycon yxg?
(its for a b&w subwoofer power board and amp board both of which are covered with chemi con SMG caps, 3 of which are faulty) - both the smg yxg are labelled as general purpose.
thank you all for your kind patience
