I have to agree with Rich on this one !
I can not speak for Nichicon but the life and derating curves for the CDE
380 85c and 381 105c series show a much longer expected life span when
both are run at 85c. Even at 45c the 105 c cap has a significant edge.
Further, at equivalent 85c temperatures, the ripple ratings are almost
identical.
IMO, in an anode supply of an amp in the 1200W or higher category the
105c cap will make both life and economical sense.
Personally, I would not want to use the ALL Electronics specials in
anything much above a SB-200 size amp without running temp and leakage
tests.
