No, it's not firm, but that is part of the fun?!
Rough guess, 35-40W.
One thing about the "X" is that it is good for an eight-ohmer, because with the bridging topology, It can get the voltage without needing excessive class A amperage. ( perhaps I'm forgetting that excessive goes together with much about pass amps...)

Aleph 4 need 48V PS and Aleph 2 need 45V and on the other hand Aleph 2 has a little higher bias then Aleph 4
I am just finishing my Aleph 4, maybe that is good enough reason

I could probably make tweaks to the Aleph-2 or 30 circuits. Power supply changes etc.. but I'm not sure I would like to burn up a pile of FETs every night, experimenting with circuit topologies.

I wonder if the existing "X" circuits sound better than the other Aleph circuits yet.

It can get the voltage without needing excessive class A amperage.

Does this mean better sound with smaller heat sinks for a given power output than other Aleph amps?

What made you go with the Aleph 4 over the 2?

You can allways convert Aleph 4 to Aleph 2 including transformer's voltage by adding air-choke, but can't go from Aleph 2 to Aleph 4.

That was one of the reasons

after speaking with the owner of Ellis Audio, he mentioned he is currently using a PP EL34 amp to power his with plenty of authority... that's only 40 watts. Might open up other possibilities... Aleph X maybe?
