I will likely sell at least a pair of Aleph 0. They both seem to be working fine, both reach temps in the high 120's after 4 to 5 hours of play. One has a ding in the top of the rear cooling fin (it looks like these can be flipped over so it wouldn't show).
The serial numbers are 4009 and 4010.
I'm leaning toward using an Aleph 0s and a 3 for my 802's. Still debating.
That would leave me with an additional pair of Aleph 3. Have not checked out any of the 3's but the other amps are performing admirably as far as my ears can tell.
