Aleph 3 safe to operate?

I've just found a Pass Aleph amplifier (6 of them actually) at an audio hoarder estate sale. It's a new in the box Aleph 3. Would it be safe to turn on without having to purchase a Variac first?

Also, I think I'd like to use it and another Aleph amp to power a pair of B&W 802 S2 with North Creek crossovers in a bi-wire configuration. If I use an Aleph 3 for the mids and highs what would the consensus be for the best amp to use for the bass drivers - I can choose from a pair of Aleph 0, an Aleph 0s, an Aleph 5 or another 3.

Also, I am currently using a Threshold Stasis 3 that was updated a number of years ago by Jon Soderberg and have been happily living with it and my North Creek Borealis' for a long time. Keep the Threshold or sub one of the aforementioned. I can't keep all of them per wife - DOH!

Thanks for your opinions

Thanks for the replies - I'm currently listening to a pair of Aleph 0 and now I'm REALLY not sure what to do. Anyone ever check the electric bill after a month of listening to these for four or so hours a day?

Jasonbourne, I do love the Stasis 3 but how well will it mesh with any of the Alephs? Would you use it over a pair of 3s for example?

Thanks all - I'll go with contacting Mr. Pass.  Appreciate all the good advice!

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.

Pass Labs got back to me and Kent says if I’m getting zero hum through the speakers that the caps are likely OK. I’ve tested five of the six for 5-8 hours each (except the last Aleph 3), mostly on my B&W Signature 805 and all sound great with zero hum. I’m loving it. My current thinking is I will part will the pair of 0 and the 0s and keep the three 3’s (one as backup).
