That said, just about any of the good brands' non-aqueous low impedance series should do well:
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.

FR is an aqueous series AFAIK, similar specs to HE. All very good caps. Since this amp used SMG, I would preferably stick with the same class of caps, but using higher temperature variants. KMG, NHG and VZ would be most appropriate choices for the intended design.
